At The Heart Of Gas Detection

4CM High performance sensing for challenging environments.

4CM High performance sensing for challenging environments.

VELOCITY In industrial safety, speed of response can be the difference between life and death. The 4CM carbon monoxide sensor from City Technology offers the fastest response and recovery time in the most challenging environmental conditions, out-performing any sensor on the market today. Conforming to the world’s most stringent Chinese mining legislation, the 4CM performs flawlessly in the wide variations of temperature, humidity and pressure found in industrial applica-tions throughout the world. What’s more, the sensor’s superb accuracy, stability and repeatability, provides users with a critical 10% extra warning time of a developing CO hazard, whilst significantly reducing instrument calibration costs.
