Fixed Oxygen (02) Gas Detector Details

Tips: Why you need an oxygen gas detector?

Oxygen detection is very important for entering confined spaces and entering certain open spaces below the ground. Other gases with higher density than air (such as gasoline, hydrogen sulfide, etc.) will accumulate in the downward direction, thereby displacing O2 in the space. There are two concentration points to consider in the detection of oxygen concentration: one is that too low O2 concentration will cause suffocation, and the other is that excessive oxygen exceeding the constant may cause unimaginable acceleration and enhancement of combustion or other chemical reactions. The concentration of oxygen in normal air is about 20.9%, and the balance (over 78%) is mainly nitrogen, and the rest includes a small amount of water vapor, carbon monoxide and other gases.

Most confined space standards and law enforcement agencies, such as OSHA, use the volumetric concentration of O2 to determine whether it is insufficient, and the usual lower limit is 19.5%. This is also the lowest alarm point set by most manufacturers on the oxygen gas detector. Some law enforcement agencies also use partial pressure of gas instead of concentration to indicate insufficient oxygen. In this case, if the O2 partial pressure is lower than 16.3 kPa or 122 mHg, it is deemed insufficient (16 kPa oxygen partial pressure is approximately equivalent to 16.3% oxygen concentration at sea level). The reason for using partial pressure is that the human body relies more on oxygen partial pressure rather than concentration for breathing.

Existing reviews of Fixed Oxygen (O2) Gas Detector, 0 to 25% / 30% Vol
Good performance
I recently acquired the Fixed Oxygen (O2) Gas Detector for our industrial facility, and I couldn't be more pleased with its performance. Its precision in monitoring oxygen levels within a broad measurement range, coupled with straightforward installation, has streamlined our safety protocols.

I have a question about your gas detector
I am Watanabe from Japan and I'm a postgraduate student. I'm writing to you for the first time.
I'm contacting you to enquire about <Gas-H2>.
I'm interested in your product and I want to use it to measure H2 in the air. So I have questions about your product.
Is this machine high precision? It's said that there is about 0.5‰H2 in the air, so I wonder whether this machine can measure by after the decimal point.

Yes, our gas detector can measure H2 in the air, and you can choose the measurement range 0-10 ppm (accuracy 0.001 ppm), or 0-500 ppm (accuracy 0.1 ppm).
Can you help me find a suitable instrument for measuring formaldehyde gas?
I want 7 of these units to be able to monitor from 0 to 100ppm of formaldehyde. We will use these inside a hatcher to monitor the levels as the chickens hatch out. I need to monitor for 3 days and I need the data to be able to be graphed out. Can you help me? Do you have a picture of the graph or does it just get exported to excel and then I have to do it myself?

1. The most common working time of our Portable Formaldehyde (CH2O) Gas Detector is 24 hours (after full charge). Therefore, if you want to exceed 72 hours working hours, then we recommend using fixed (CH2O) gas detectors, it can run continuously for a long time.
2. Whether you will use our portable or fixed gas detector, you can only export the measurement data to the excel file without providing the historical graph.
