carbon monoxide sensor
FEATURES
Design for real time detection and monitoring carbon dioxide and temperature. Humidity detection is optional
Particular LCD display with three color backlit (Green/Yellow/Red)
CO measurement range: 0~500ppm/0~1000ppm
Electrochemical CO sensor with up to 5 years lift time
Two stages alarm preset
Two alarm ways: buzzer alarm and backlight colours changeover
Provide up to 2 relay dry contact outputs to control a fan and an alarm
Provide 1X analog linear output (0~10VDC/4~20mA selectable) for the measurement
Modbus RS–485 communication interface, 15 KV antistatic protection, individual IP address
Replace the CO sensor by the end user available
Provide two easy methods for calibration and setup alarm points by end users: infrared remote controller or a software via RS485
Humidity measurement and display optional
24VAC/VDC power supply, also 230VAC power supply with a power adaptor
For more applications with wall-mounted type and portable type
Great performance with higher quality and lower price
