Personal Gas Monitors
Crowcon Gas-Pro is a confined space entry monitoring solution for workers and fleet managers, and is now supported by the Crowcon I-Test bump test and calibration


Offering detection of up to 5 gases in a compact and rugged solution, Gas-Pro has an easy-to-read top mount display combining ease of use and user focused features.

An optional internal pump, activated with the flow plate, takes the pain out of pre-entry testing and allows Gas-Pro to be worn either in pumped or diffusion modes

NEW! IR Sensor Technology
Gas-Pro IR detects potentially explosive gases in conditions where a pellistor-based catalytic sensor may struggle, especially in a low oxygen environment. The infrared measurement gives improved reliability and measures gas in two different wavelengths: one that absorbs gas and the other does not. With little chance of being poisoned, the Gas-Pro IR is inherently safer and saves the need of regular and expensive pellistor replacement when used in likely contaminated environments.
