Catalytic Type Gas Sensor

Supply voltage DC 2.5±0.25V
AC 2.5±0.25V(r.m.s. 50-60Hz)
Current (2.5V supplied) DC 160 - 180mA
AC 160 - 180mA(r.m.s. 50-60Hz)
Ambient Temperature In operation -20 - +60°C
In storage -30 - +70°C

Ambient humidity


In operation 95%RH or less
In storage 99%RH or less(No dew condensation)


The sensro can detect combustible gases except ethanol from 1 to 100%LEL, but excellent linear measurement appears within the range less than 50%LEL which can provide accuracy of less than ±10%. NAP-52A is suitable for indoor detectors and recommended to be applied within 50%LEL.
