Carbon Monoxide (CO) Detectors

We supply a wide range of fixed and portable carbon monoxide gas detectors for industrial and personal protection. Fixed monitors provide continuous coverage in facilities such as boiler rooms, manufacturing plants, and tunnels, while portable units are ideal for workers in variable or confined environments.

Our range includes detectors from BW, Honeywell, Crowcon, Dräger, Gas Data, Green Instruments, GMI, ION Science, MSA, RAE Systems, Riken Keiki, and Senko, all trusted globally for their robust designs and advanced detection technology. Portable CO detectors may also be available for hire.

Protect your workforce from the dangers of carbon monoxide with our fixed and portable detection solutions, trusted across industries worldwide.

Detection is achieved through electrochemical sensors, offering high sensitivity, rapid response, and stable performance across workplace exposure ranges. With routine calibration, these detectors deliver accurate and reliable protection in compliance with occupational safety standards.

Carbon monoxide (CO) is a colourless, odourless, and highly toxic gas produced by incomplete combustion of carbon-based fuels. It is a significant hazard in industries such as mining, steelmaking, shipping, tunnelling, and confined space entry. Even at low concentrations, CO binds to haemoglobin in the blood more readily than oxygen, reducing the body’s ability to transport oxygen and leading to symptoms such as headaches, dizziness, and, at higher levels, loss of consciousness or death. Because it provides no warning signs, continuous monitoring is essential.
