1.Electrochemical CO transmitter 2.0~10VDC or 4~20mA output selected by jumper 3.RS485 communication
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
