Electrochemical Carbon Monoxide Sensor EC-4CO-500
EC-4CO-500 is a CO sensor which detects Carbon Monoxide in level from 0~500ppm for industrial application.
Response speed of the Carbon Monoxide(CO) Electrochemical Sensor is very fast, it is in compliance with most of world-wide industrial standards, and it is also applicable for wider fields.
The CO Electrochemical Sensor can be retrofitted easily to existing product designs.
