GAS-PRO IR

The Gas-Pro IR is ideal for the oil and gas industry. This personal multi–gas monitor solves the challenges faced by traditional pellistor catalytic sensors, detecting gases such as methane, pentane or propane using infrared (IR) technology even in low oxygen environments.

Where to Buy

Harness the power of infrared (IR) technology for additional peace of mind across your site with the Gas-Pro IR portable detector.

The infrared measurement gives improved reliability and measures gas in two different wavelengths: one that absorbs gas and the other does not. The %LEL of gas present is determined by the difference in intensity between the beams measured by the photo-receiver.

With little chance of being poisoned, the Gas-Pro IR personal multi gas detector is inherently safer than traditional pellistor catalytic sensors, and saves the need of regular and expensive pellistor replacement when used in likely contaminated environments.

Simple to use and with easy testing and calibration, the Gas-Pro IR now completes the Gas-Pro range and gives greater flexibility for sensor selection in this 5-gas multi gas detector.

Detects up to 5 gases

Reduced risk of device poisoning

Intuitive functionality

Portable & durable

14+ hour battery life
