@@fotongammadosimetry Chinese made Geiger tubes are often made from glass, not from metal, hence the natural light will trigger ionisation of the gas inside it once you dissemble the counter and expose the tube. The counter must be turned on of course.
@@ToMi-bm5hh no. Modern chinese, glass geiger tubes dont react to UV from sunlight. I checked many dosimeters :) Guy just dont know what he is measuring.
@@ToMi-bm5hh i have a lot of chinese made dosimeter with glass tubes and they dont react to UV. I made tests by myself. Please check what your saying :)
You might want to take a look at the review of the GC-01 I just released on my channel. Sadly the product has just switched to a far inferior GM tube and this even includes the white-label versions of this device. I contacted the company here in China (where I am based) and they confirmed the change. Such a shame, its was pretty OK for a low cost counter...
Ps, there was no 5th screw on mine so I damaged the sticker for nothing, I don't know if that's common for older models but I hope so, saves time, I was lucky.
Mi estimado, espero me puedas ayudar, tengo ese mismo medidor de radiación, pero no se bien como cargarlo correctamente, cuando lo conecto para cargar, se enciende y carga, pero si lo quiero apagar, se apaga y se vuelve a encender solo, es esto normal, espero puedas ayudarme, saludos.
la computadora no me lo reconoce, lo conecto y si carga, pero no me aparece como unidad, como se mantiene encendico, me imagino que por eso no lo reconoce la compu. @@inventorkr1
Muchas gracias por tu atención y paciencia, contacté con ellos y me dijeromn que no era original, verifiqué los componentes del circuito y no corresponden al diseño original, o al menosal actual, hasta en eso hay que tener cuidado, y es que el aparato se ve idéntico en todos los sentidos. @@inventorkr1
It dont need it. It could be no accuerate for be cheap. So if it doesnt measure correctly probably is for that. So there are likely wsy to fix that but is someting that only expert in the topic can do it.
No funciona, no enciende cuando aprieto el botón de energía, lo he puesto a cargar toda la noche y no hace nada, ni presionando rápido ni dejando pulsado unos segundos...
@@2nostromo I watched it from other videos, which mentioned: If you want to test radon, you need to use a vacuum cleaner to suck the test site for about 10-15 minutes, then take out the filter to test it. The above is for your reference. I am not sure whether it is correct or not.
Perfect!!! This is exactly what a product video should be like! (for such gadgets) In particular I want to thank you for opening it and showing us the battery. This has literally cleared all questions I had regarding this device - you nailed it bro!
No, a good video would be explaining things about this, explaining what it can or can't do, explaining what everything is when they took it apart, this unfortunately not that kind of video.
Добрые люди,не покупайте это дерьмо.С осени 2023 г. китайцы начали устанавливать вместо счётчика Гейгера J321 другой тип прибора с очень низкой чувствительностью--J615. С J615 прибор стал просто дерьмо! Не тратьте деньги на Fnirsi,у них все дерьмо.
This is crappy telling people they (indirectly) need this device to the point it will change their life. Yes maybe if you live in Ukraine. Yes there are a few other circumstances... but crap like this plays on people's fear. While the TH-camr has a vested sponsored interest in the product. Not cool. Not that would anyone care but I am unsubscribing for this reason.
I appreciate your feedback, but could you please specify what exactly you found confusing or unclear? I'm always open to improving and making my content better for my viewers.
I took this one. Yesterday sold sent a new version of the firmware to this device. After installation, I received a brick. Doesn't turn on and doesn't respond to anything. Maybe someone has already encountered? P.S. I took it in the official store
@@inventorkr1 I did so. Technical support helped me solve my problem very quickly. The problem was with the windows software. Fnirsi is a great store and the best customer support ever!
You're mistaken ionising radiation with electromagnetic radiation. To test device, you need radioactive material.
The result is the ionization of the gas in the tube
@@inventorkr1 but you dont measure any ionising radiation source, so how do you want to make gas ionisation in tube :)

I can confirm that! Its not worth buing anymore unless FNIRSI change back to better tube. For the moment its garbage!

Дожился,смотрю обзоры на счётчики Гейгера)
Ich finde es komisch das auf manchen Website das selbe Model für 150EUR 110EUR oder 50EUR Angeboten wird
Nice product👍
This looks like the power pack should be relatively easy to swap, to either replace or upgrade.
How long does the battery last, BTW?
Less than 1 hour for me, first use though.
Super 👍👏👏👏
What's with the CRO probe across the Geiger tube holder??
Hello, do you have a way to connect the counter to a computer? i would like to save the data
Hi, they have a alarm and vibration?
You can visit the store and see the number of sensors, meters and oscilloscopes available
Yes and yes
They do have an alarm at the bell door. As for the vibration check the dildo section.
looks good, but wished you could of explained to us what you were doing
Meaning what the buttons do as no idea.
Obviously looking for radiation sources being that this is a Geiger counter
@@madmax2069 I never thought to read the box and also learn chinese to understand what the controls actullay do
@@spudnickuk well the thumbnail having a radiation symbol is enough to be able to figure out what it is.
Just wish the divice could make click noise / incident.

Does this detect Radon in homes?
Some people need to measure Radon levels in their basement and have it automatically turn on ventilation when it goes over a setpoint.

@@2nostromo Look up the radostat. No idea how much it costs but it will turn on a fan when it detects high radon levels.

How did you manage to remove the central screw without damaging the label, please?
peel the label off
Is this a question for the low IQ persons?
The older ones have no screw. Under the label.
