The Crowcon T4x is a gas detector for Carbon Monoxide, Hydrogen Sulphide, Flammable gases and Oxygen depletion.
T4x is a rugged device with a large single button and an easy-to-use menu system. It can be operated with gloves and minimal training. An integrated rubber boot is supplied, and an optional clip-on filter cover to protect the sensors in dirty environments. It is water-resistant with IP65/IP67 ratings, has been drop-tested to 4m and is Zone 0 approved.
Eliminates poisoning and cuts the number of sensor replacements
Achieve more with fewer resources, T4x eliminates poisoning and cuts the number of sensor replacements by 75%. Only one sensor needs replacing over the device’s lifetime.
Go to the gas detector for all confined spaces involving oxygen
T4x is the only go-to gas detector for all confined spaces involving oxygen, as it detects over 15 flammable gases, including pentane, hexane and other long-chain hydrocarbons and O2, H2S and CO.
Enhanced battery life
35+ hours battery life (double the battery life of our original T4) allows multiple or longer shifts to be worked between recharging.
Sensors
T4x is available with the following sensor options:
| Sensor | Warranty | Expected Life |
| Oxygen | 3 years | 3 years |
| Oxygen (Long-Life) | 5 years | >5 years |
| Flammable (pellistor) | 2 years | Up to 5 years in air |
| Flammable (MPS) | 5 years | >5 years |
| Carbon monoxide | 2 years | >2 years |
| Hydrogen sulphide | 2 years | >2 years |
MPS: Advanced molecular property spectrometer (MPS) sensor technology that detects and accurately identifies over 15 different flammable gases in one device.
Dual Toxic: Utilising a three-year life dual toxic sensor (CO and H2S). You get the same performance of individual sensors in one package, reducing costly replacements with tried and tested technology.
Long-life Oxygen: This long-life Oxygen sensor with a five-year warranty and RoHS lead-free compliance saves you money and delivers on safety and environmental regulations.
