Tips: How do I use a nitrogen dioxide gas tester to detect a leak of nitrogen dioxide gas?
To detect a NO2 gas leak, first make sure the tester is properly calibrated and charged. Then, place the gas detector close to an area where there may be a leak, such as a pipe fitting, valve, or gas storage tank. Start the unit and observe the NO2 concentration reading on the display. If the reading is outside the normal range or reaches the preset alarm value, there is a NO2 leak and immediate safety measures need to be taken.
