Quick response

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.
