General Description:
The NAP-505 Gas Sensor is a new, low–cost 3-electrode
electrochemical cell designed for the detection and
measurement of carbon monoxide in the range 0-1000ppm, in domestic
carbon monoxide detectors, fire detectors and air quality monitors.
Features:
- 3-Electrode
design for greater stability
-
Compact, leak-proof
enclosure
-
Resistant to shocks and vibration
- Terminals
may be soldered
-
Linear output
-
Highly specific
to target gas
- Unaffected
by humidity
-
Very low long term drift
-
Low power
consumption
