Crowcon Gas-Pro TK – Hydrogen Sulphide (H2S), Carbon Monoxide (CO), Oxygen (O2) Gas Detector – call T&D Sales for price, delivery and stock.
Multi Gas Detection
Crowcon Gas-Pro TK
The Crowcon Gas-Pro TK is portable multigas detector, which protects against the four most prevalent gas hazards: carbon monoxide (CO), hydrogen sulphide (H2S), flammable gases and oxygen (O2) depletion or enrichment.
Gas-Pro TK (previously Crowcon Tank-Pro) is a tool for monitoring inert tanks or pipes as well as being a personal multigas monitor. This portable gas detector offers integrated innovative safety features with a rugged design to provide advanced protection for those working in harsh environments.
The Gas-Pro TK specialised personal tank monitor with dual range sensor is water and dust resistant to IP65 and IP67. Complimentary accessories include; multiple charging options, pumped flow plate, chest harness straps and portables Pro 2.0 software for accessing advanced features and data logs.

See how the Crowcon Gas-Pro TK (previously known as Tank-Pro) gas detector provides reliable, lightweight and maintenance free detection of toxic and flammable gas in Zone 1 and Zone 2 hazardous areas.
Gas-Pro TK employs the best sensor technology to reliably monitor inert spaces – dual infra-red (IR). IR sensors are not inhibited by high hydrocarbon concentrations and don’t require oxygen to work. Unlike single IR sensors, the dual nature of this sensor enables it to cope with gas in high %vol. as well as %LEL concentrations. An integrated pump quickly draws samples from lines up to 30 metres long, so tanks and pipes can be checked quickly and efficiently.
