The Crowcon T4x portable gas detector is Crowcon’s zone 0 approved personal protection solution for detecting the four most common gas hazards:

  • Carbon Monoxide (CO)
  • Hydrogen Sulphide (H2S)
  • Flammable Gases (MPS)
  • Oxygen Depletion (O2)

Now available with improved detection of pentane, hexane, and other long-chain hydrocarbons; offering compliance and low cost of ownership in a simple, familiar to use solution. The large single button and intuitive menu allow the T4x to be operated whilst wearing gloves with minimal training required.

T4x compliance badges

The Crowcon T4x is by design a durable portable gas monitor, incorporating an integrated tough rubber boot as standard.

Drop tested to 4m and well protected from water ingress through IP65 and IP67 certification, the T4x allows uninterrupted working, even in the most demanding environments.

An optional clip-on filter cover helps prevent pollution, and can easily be removed and replaced as needed, ensuring sensors are protected, even in the dirtiest environments.

Achieve more with less 

The T4x gas detector eliminates poisoning and reduces the number of sensor replacements by 75% only 1 sensor needs replacing over the device’s lifespan.

“Detects more than 15 flammable gases at once straight out the box”

The Crowcon T4x is the only goto gas detector for all confined spaces involving oxygen, as it detects more than 15 flammable gases at once straight out the box, as well as oxygen, H2S and CO.

Enhanced battery life

With 35+ hours of battery life (double the battery life of our original T4) the T4x allows multiple or longer shifts to be worked between recharging.

Sensor types

MPS: Advances molecular property spectrometer (MPS™) sensor technology that detects and accurately identifies over 15 different flammable gases in one device.

Dual Toxic: Utilising a 3-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 5-year warranty and RoHS lead-free compliance saves you money and delivers on safety and environmental regulation.
