Gas detection specialist Crowcon has further strengthened its Gas-Pro range with the introduction of the Gas-Pro IR.

This latest offering detects methane, pentane or propane using infrared IR sensor technology.

“The Gas-Pro IR detects potentially explosive gases in conditions where a pellistor-based catalytic sensor may struggle, especially in a low oxygen environment, as pellistors need oxygen to function,” said Richard Dunn, Portables Product Manager, Crowcon.

“Also, in some industrial environments, pellistor sensors are at particular risk of being poisoned or inhibited, so leaving workers on their shift unprotected. In such environments, use of IR sensors significantly enhances safety and saves the cost of regular pellistor sensor replacement.”

The infrared measurement gives improved reliability over pellistor-based sensor systems.

A key advantage of the IR system is its application in low oxygen environments, particularly in confined spaces where the movement of air/gas is naturally restricted. In places such as fuel storage tanks, where an inert gas has been flushed through prior to maintenance, the low oxygen environment (typically, under 5% of the local atmosphere) means a pellistor-based sensor could not be relied on to test the level of fuel vapour.

The Gas-Pro IR carries forward the simple calibration and easy testing that is synonymous with Gas-Pro range. The Gas-Pro IR range now completes Gas-Pro range, which gives greater flexibility for sensor selection in a five-gas multi-gas detector.
