NAP-50A Catalytic Pellistor Gas Sensor Light Commercial Applications All Flammable Gases
Product Description:
NAP-50A Catalytic Pellistor Gas Sensor Light Commercial Applications All Flammable Gases
Features:
Nap-50a is a small size and low power sensor. Nap-50a is mainly used for gas detection. Compared with NAP-55A, NAP-50A has less interference to the alarm caused by alcohol, and the gas detector made by NAP-50A is more reliable. The following are the basic parameters, but it is for civilian use, see the user manual for more information. Refer to the sensor test circuit of NAP-66A.
*Measures flammability directly
*Highly resistant to Catalyst poisons
*Complies with EN50194 standard
*Effectively Linear output to 50%LEL
*Specific to flammable gases
*Unaffected by Humidity
*Very Simple circuitry
*Very Low Long term drift
