       Electrochemical CO Transmitter with high accuracy

¨  Features

u  Wall mounting, real time detect CO level with measuring range of 0~100ppm/ 0~200pm/ 0~500ppm.

u  Electrochemical sensor which offer several advantages over traditional electrochemical sensors.

u  With a long life, good long term stability, and high accuracy, the CO sensor is environmentally friendly without risk of electrolyte leakage.

u  With simple calibration

u  The special design of easy sensor’s replacement makes customers replace sensor easily by themselves

u  Full time CO level detection, even the slightest leak can be detected

u  One analog output of the measurement of carbon monoxide concentration with 0~10V/4~20mA selectable

u  Special built-in Self-Zero Correction algorithm.

u  Modbus RS-485 communication with 15KV antistatic protection, also can be calibrated carbon monoxide measurement via the interface

 Application

u  Residential and commercial CO detectors and transmitters

u  Ventilation control for indoor parking garages

u  Recreational vehicle CO detectors

u  Kitchen rooms and restaurants

u  Freezing machine rooms and other places where air quality is easy to worsen
