Gas sensing expert, City
Technology, has introduced 4CM, a
new carbon monoxide sensor
designed for use in the most
challenging environments.

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

City Technology says the 4CM
responds 12% faster to CO hazards
and that it recovers in less time. This
is a benefit to detection instrument
manufacturers keen to improve the
performance of their products.
