Specification

SENSOR SPECIFICATION
Measurement technology
High-performance NDIR
Measurement Range
0 - 100% LEL Flammable Gas, equivalent to 0-5% Vol of Methane (CH4)
* for the C3H8 gas application, please consult us before ordering
Maximum response time (T90)
< 40s
Resolution
500 ppm (at 5% Vol)
The resolution will vary with gas concentration due to the non-linear response to the target gas, therefore the best resolution will be at the low concentrations and will get worse as the concentration increases.

Maximum deviation from linearity

± 0.1% vol

Maximum variation of zero from −20 to +55°C

±30 ppm/°C

Maximum non-reproducibility of zero at 20 °C

±500 ppm

Maximum non-reproducibility of sensitivity at 20 °C

<± 1000 ppm

Long-term zero drift/month

±500 ppm

Response to 0-90% change in RH at 20 °C (in target gas)
