Low-Cost Electrochemical Toxic Gas Sensors for Residential and Light Commercial Applications

NAP-508 Electrochemical Carbon Monoxide Gas Sensor



General Description:

The all-new NAP-508 Gas Sensor is a low–cost 3-electrode electrochemical gas sensor designed for the detection and measurement of carbon monoxide in the range 0-1000ppm, in domestic carbon monoxide detectors, fire detectors, air quality monitors and commercial gas detection applications.

Drawing from Nemoto’s considerable experience with the established and very popular NAP-505 sensor, the NAP-508 represents the next generation of low-cost CO sensors from Nemoto, benefiting from a warranted 10 year life when used in a residential or light commercial environment
