New from City Technology, the 4CM
carbon monoxide sensor is designed
for use in challenging environments.

Developed to meet the most stringent
toxic gas and mining standards, the
4CM is said to not only improve the
functionality, reliability and
effectiveness of PPE in hostile
environments, but to demonstrate a
high level of performance and
stability in temperature and humidity
extremes.

The 4CM is said to respond 12%
faster to CO hazards than some
sensors and to recover in over half
the time of the industry average, a
key benefit to detection instrument
manufacturers keen to improve the
performance of their products.
