How to use oxygen gas detector correctly?
1. Oxygen detectors, as we all know, are used to test oxygen concentration. Some are used for human safety to prevent hypoxia, and some are used to control the oxygen concentration from being too high to avoid the risk of explosion, because oxygen has combustion-supporting properties. Another purpose is to Check oxygen purity;
2. Pay attention to the conditions that the ambient temperature you test should not exceed your own requirements, which is generally -20 to +50 degrees, the humidity is 95% without condensation, the atmospheric pressure is normal pressure, and there is no large amount of gas dust. It is necessary to calibrate regularly, generally once every 3-6 months. Oxygen detector calibration is relatively simple. You can calibrate your instrument based on the standard oxygen content in the air.
3. At this point, let's talk about something that friends often ask during use: Why does my oxygen detection instrument have problems after I bought it but haven't used it a few times? The data display error is so big, the instrument Basically it's still new. If you buy it and store it without using it much, it will still look like new after one or two years, but why does the detector have problems? That's because there's something wrong with the oxygen sensor performance;
4. For many of our portable oxygen detectors, if they are not used for a long time, the battery will also have over-discharge problems, resulting in the inability to charge when used later. Here is a little trick for you. If this phenomenon occurs, you can use it. A 1-2v charger that is slightly higher than the original charging voltage activates the battery charging, so that the battery charging problem can be restored and the problem of being unable to charge can be solved;
5. Through the above understanding of oxygen detection instruments, it is not difficult to see that the correct way to use it is actually not complicated. Start up---preheat---working conditions permit--direct measurement 1 -Read in 2 minutes---Shut down---Occasionally turn on during storage period to warm up--Calibrate--Save for next use.
