Technical Information



NAP-52A is a newly developed contact combustion gas sensor that can detect hydrocarbon-based combustible gases. This product consumes electrical energy and the position of pins is equivalent to our conventional model NAP-50A. The improved NAP-52A The ability of organosilicon vapor has been improved. At the same time, it has the same anti-alcohol interference performance as NAP-50A, but its detection sensitivity to combustible gas is lower than that of NAP-50A.

Supply voltage: AC 2.5 ± 0.25V (50-60Hz), DC 2.5 ± 0.25V

Current (when 2.5V is added): AC 160 ~ 180mA (50-60Hz), DC 160 ~ 180mA

Ambient temperature and humidity during use: Temperature -20 ~ + 60 ℃ Humidity, below 95% RH (non-condensing)

Ambient temperature and humidity during storage: Temperature -30 ~ + 70 ℃ Humidity, below 99% RH (non-condensing)

Can detect 1 ~ 100% LEL flammable gas (except ethanol gas), but excellent linear measurement indicators appear in the range of less than 50% LEL, can provide linear measurement accuracy less than plus or minus 10%. This sensor is suitable for indoor use, and it is recommended to use it in a concentration range below 50% LEL.
