- In this quick video, Bryan goes over some of his best tips on how to clean a micron gauge. Dirt and contaminants can get on the sensor of a micron gauge, so you would greatly benefit from knowing how to clean yours.
To prevent contaminants from getting into the micron gauge in the first place, we recommend attaching your micron gauge to a core removal tool (CRT) in a way that allows the gauge to sit upright. When the gauge is upright, oils and contaminants are less likely to get in through the bottom. Some technicians will even use a configuration of 3 CRTs to make sure they can connect the micron gauge in an upright position.
You can clean your micron gauge by removing the cap and applying isopropyl rubbing alcohol to the port of the micron gauge through an eyedropper, pipet, or eyedrop container (but be sure to label the container if you use one of those). According to Jim Bergmann, you may even choose to use a high-quality contact lens solution to clean the port. Then, you cap the port, tip the micron gauge, and shake it lightly. After shaking the micron gauge for a little bit, you can reopen the cap and pour the alcohol or cleaning solution out of the port. You can repeat this process a few more times until the micron gauge is clean.
When you think the micron gauge is fully clean, you can wipe it down with a rag and put it back into service.

I just use tequila. I always have some in my van for in between service calls anyway.
I like the way you think G!
Great ideas 😄💡 must have Alcohol/ liquor in the Truck All time 👍
Can you also show how to clean tru blu hoses if they get contaminated by oil.
Hi Bryan, So you don't recommend using a spritz of Nitrogen after the 1 or 2 cleaning douches of alcohol to help dry it out, but just let it air dry? Thanks much, Bob
Rubbing Alcohol worked great on a malfunctioning pressure transducer for EXV. Just FYI. Another reason to have some on your truck. I'm a BluVac fan as well, by the way.
That's good to know!
CPS recommends denatured alcohol.
I recently had to pull a vacuum on a system I only later realized had insane oil migration. Despite the micron gauge standing upright, the sensor was smothered in oil. I removed the Schrader depressor and poured alcohol in a few times, and it still struggles to read accurately. I'm probably just going to have to get a new micron gauge.
My bluvac mini reads oil after 2 uses. I use my old compound vacuum gauge.

What about CRC contac cleaner ?
So this procedure is good for digital gauge manifold too?? ei..Testo 550, higher or Fieldpiece
Yes
My fieldpiece micron gauge doesn't hold and only reaches 690 microns but still it wouldn't hold I tried it directly on my vacuum pump and it reaches 69 and fluctuates back to 179 doesn't stay one place what can cause this does anyone know I cleaned it blow a bit of nitrogen in it but still same thing
Can you use Isopropyl-Alcohol to clean the inner-lining of hoses too?
Yes. You can. Remember to purge it with air compressor
Don't you mean compressed nitrogen?
@@paulf1071 yup.. Nitrogen purge much better.
Isopropyl for the gauge and alcohol for the operator, got it. Oh, it doesn't go in the eyes.
How this sensor works ?
It has a tiny heater and it measures how quickly that tiny amount of heat dissipates. The less atoms present to get excited by the calibrated heat source the slower the heat dissipates and therefore we can get a measurement. Pretty ingenious if you ask me. The tiny heater gets covered in oil and throws the whole thing out of whack.
@@jamminwrenches860 thanks
Hey guys can you use this trick on a Fieldpiece SM480V
Rubbing alcohol leaves a residue, wouldn't an electronics cleaner work better?
That will also work fine, I've had no issues with alcohol
Way cheaper to just get a ball valve instead of using a second CRT
