Crowcon Gas-Pro IR Multi Gas Detector

Overview

Crowcon Gas-Pro IR Multi Gas Detector

The Crowcon Gas-Pro IR Multi Gas Detector is a rugged, portable up to 5-gas detector featuring advanced Infrared (IR) technology for combustible gas detection. Designed for marine, offshore, oil & gas, petrochemical, and confined-space applications, the Gas-Pro IR provides superior reliability in environments where catalytic (pellistor) sensors may become poisoned or fail. The infrared sensor operates even in oxygen-deficient atmospheres, making it an excellent solution for demanding industrial environments. Available in both diffusion and pump-operated versions, the Gas-Pro IR combines long battery life, intuitive operation, and rugged IP65/IP67 protection for maximum workplace safety.
