You say to store the probe with droplets of water, but the you say never to store with RO or distilled water. Can I use drops of ph4 buffer instead to store?
I used to own Blue Labs ($95), I broke it, bought this, $50, THESE hold calibration better. I test daily. Every 2 weeks calibrate her. But again, I use daily 5 different tests.
After a year of use looking really well after it I can no longer calibrate, as the reading of the 7 buffer reads as Ph 8 and wont calibrate, it throw the error er1.. Any solutions or I need to get a new prove/device!? If so I am very disappointed with the product! The only reason I choose you it was cos I though yours will be better, but it did not last more than any regular 20$.. Not worth the extra 40$ by any means.
We are sorry to hear this happening to you. It could be due to contaminated buffers, aged probe, or malfunctioning instrument...we need to test on the product to identify the root cause. You can go to support.aperainst.com to submit a RMA ticket. One of our technical support will be in touch to help you resolve the problem.
How often should you calibrate the meter before using it? Is there already a built in sensor to notify when its time to calibrate? Or once a week?~ Thank you!
Frequent Use: Calibrate at least once a week. Moderate Use: For regular, moderate use, calibrate at least once a month. This is generally sufficient to maintain accuracy. Special Situations for Recalibration: * After testing highly acidic (pH < 2) or highly alkaline (pH > 12) solutions. * If the tester has not been used for an extended period. The PH20 tester does not have a built-in notification sensor to alert you when recalibration is necessary. You will need to follow the guidelines above or check calibration solution periodically if stability issues or accuracy deviations are observed.
Hello, I just got the PH20 PH tester, but I read in the instruction manuel that: if you find any air bubble in the glass bulb of the PH sensor, simply shake the probe for a few times to remove it. But isn't it normal that their is an air buble? Because I tried and get rid of the air buble, but with no succes. Thanks.
So, if water isn't for storage, how are the water drops that maybe in there when it's brand new any good for it??? I've always kept drips in my ph pen caps to keep diode from drying up. Wtf do I putting it then? Drops of ph 4 buffer???? Cuz it sure didn't come with storage solution and idk why tf ot wouldn't
Hello! We are sorry about the confusion there. Leaving a few water droplets is only for maintaining a humid atmosphere in the probe cap to prevent the pH membrane from drying out. It’s different from soaking/immersing the pH probe in water, which is going to damage the probe gradually. Using 3M KCl soaking solution to store the pH probe is the best practice that can keep the pH sensor at its optimal condition. As people might not always have 3M KCl on hand, the alternative is soaking the probe in pH 4 buffer. When you don’t have pH 4 buffer on hand either, leaving a few water droplets in the cap is going to be much better than dry storage. To put it simply, there is a ranking for pH probe storage method, from worst to best: soaking in pure water like tap or drinking water (Very bad) --> dry storage (Bad) --> leaving a few water droplets in the probe cap (OK) --> soaking in pH 4 buffer (good) --> soaking in 3M KCl soaking solution (best). Hope you can find this info helpful.
@aperainst hey I have this new meter that I got when we were talking about storage...hlf the time I open the case,take it out and hit the button, and it doesn't turn on. That sucks, because what am I supposed to do the whole time this is in the mail going back to u guys AND the time it takes for a replacement to reach me? This sucks. And it won't turn on right now at all. I finally after 3½ yrs of using cheap junk throw away meters, went for it and bought an apera instrument. And here I am lol what am I supposed to do about this? Email?
@aperainst even the day I got it, I calibrated it. There was a couple times it shut off before I could dip into the 7 solution, to water,and to the 4ph. Couple times I had to hit the power button a few times cuz it wouldn't turn on. Now it's still not turning on with 50 gallons of plant food mixed up for use this evening. It's an expensive mix every Friday believe me. This is about to go to waste I have a feeling🤬
Mine only came with buffer 4 and 7. Do I need to buy the 3rd buffer before I use it? This is not good. Even the cheap vivosun ph meter came with all 3 buffers and this one was 3x the cost.
Hello, I have the Storage solution 3M-KCl and I have filled the cap of my PH tester with the solution to the fill line. But do you need to put the probe of the PH meter always in the storage solution or just overnight? Thanks
I wouldn't do that as above and in their tutorial they say only store in the KCL solution for long term storage and not if you use it daily or weekly. They also say store it in the ph 4 buffer solution or with just a few drops of pure (distilled water) in the cap to maintain humidity. Now I am confused too as I've heard not to store in the buffer solution and not to store in distilled water. But they're saying the KCL is just for long term storage or restoring a dried out probe.
@@jameswilliford5478 Damn all those different stuff. I just store it in the KCL solution. I guess if it's good for long term storage or restoring a dried out probe, it's good for short term storage too. Better storing it in KCL solution then nothing att all. So how do you store your PH tester?
No. Typically one calibration can hold the accuracy for about a month. But you can always check the accuracy by testing the fresh buffer, if there is discrepancy, you can calibrate the meter to get it right.
Can I or should I store it in kcl solution long term? I don't really understand this as it seeems like all the ph meter use the same techology. Still some say store it in kcl solution all the time, some say it need to be humid, or in water and some do not say anything at all. It's a pricey stuff and I want to have it the longest lifespan as it can.
For long term storage (>1 month) or restoring a dried-out pH probe, we'd recommend storing in 3M KCl soaking solution. But if you use the meter frequently (like daily or weekly), keep the storage cap wet with pure water or soak in pH 4 buffer solution will do the job.
It looks like I bought the wrong tester. I wanted to buy a tester to try to find out what the ph level is in the soil for my cannabis plants. If i'm looking at this correctly, this just tests fluids and does not have anything to do with soil.
Hi guys, have a question. When Im trying to calibrate in the first 7ph solution, my ph meter show 6.9ph and 6 on the botton of the screen insted of 7. Seems like its not calibrating. Could you provide me any solution?
You have changed the calibration standard series to NIST instead of USA by accident. It's an easy fix. Just go ahead and change it back to USA standard at settings P1. Please refer to 03:33 in the video on how to change the settings.😄
Are the solutions a one time use? Also can I use calibration solutions from other brands or does it have to be from apera only?I haven’t found any answers to this one yet. Thank!
il keep it real its just to much work with this ph bin from the word go you have to recalibrate it damn near every time you use it ,its way to finicky , you cant use tap water it has to be pure water soak 5 hours or over night i really appreciate my bluelab after using this !
Please note that pH probes should never be soaked in pure water or tap water. It should be soaked in 3M KCl soaking solution or pH 4 buffer if you don't have 3M KCl on hand.
The PH20 Tester only measures pH. It doesn't support tds measurement. Here are some pf our models that support pH and TDS dual measurement: PC60, PC60-Z, GroStar GS4.
Die Anleitungen sind ein Graus und absolut widersprüchlich, ich denke, ich schicke es wieder zurück. Da sind mir Teststreifen für ein paar Euro lieber. 😞
I appreciate the video tutorial. Im all set up!
i dip it into PH7 fluid and it reads 7.6 and when i short click it it reads er1 and i cannot do anything with it
do you find solution?
Same
Welcome to the club. This prove seems as rubbish as the 20$ ones... They don't last more than a year even looking very well after it.
Me too after 3 years however
@@anthonymurphy6649did you rehydrate the sensor?
Do i have to fill the cap with kcl solution for storage?

When you say pure water are you talking about distilled or RO water or just tap water ????
Preferably distilled water. RO water is also fine. Tap water is not recommended.
Need a video like this for the Apera 910 series please!

Hi! I just purchased the kit. It doesn't include the PH10 solution. Why is it included in the video? Is it necessary for calibration?
the video literally answers your questions 🤣1:41 and 1:51 ... any more q's that need a's? lol
Can you please tell me how to restart mine???😢

Try shaking the meter off like whipping.
Does this process have to be carried out everytime you turn it on or only once before using it the first time?
As rule of thumb, we'd recommend calibrating the meter once every month.
@@aperainst Okay thanks for the reply!
I have this pen can I replace the prob my pen is not working
You can send the unit back to our facility at 6656 Busch Blvd, Columbus, Ohio 43229. One of our technicans can help you replace the probe for PH20.

Hi! Yes, you do have to buy the 3rd solution. They also sell a CalPod for storage - it's great because you won't waste any solution. Hope this helps
Hello. Can I rinse the probe of this Ph meter in demineralized water instead of distilled water ? Thanks ;)
Yes demineralized or deionized water is perfect.
@@aperainst thank you ;)
Hello, I have the Storage solution 3M-KCl and I have filled the cap of my PH tester with the solution to the fill line. But do you need to put the probe of the PH meter always in the storage solution or just overnight? Thanks
Always storing the ph probe when it's not in use is the best practice.

what s the dif between the blue and green 1?
Blue screen is for measurement mode. Green screen is for calibration mode.
Do I need to calibrate before any pH test?
No. Typically one calibration can hold the accuracy for about a month. But you can always check the accuracy by testing the fresh buffer, if there is discrepancy, you can calibrate the meter to get it right.

pH 4 and 7 buffer solutions are good for up to 10 times of calibration as long as they are not expired or contaminated.
Are the solutions bottles a 1 time use
No, just rinse the probe off when going between the different bottles of calibration fluid to avoid cross contamination.
No you can use many times
