DatasheetT4x 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 with improved detection of pentane, hexane and other long chain hydrocarbons.
Offering you compliance and low cost of ownership in a simple to use solution. The large single button and intuitive menu system allows T4x to be operated wearing gloves with minimal training.
T4x is durable by design and includes an integrated rubber boot as standard. An optional clip-on filter cover, which is easily removed and replaced, ensures sensors are protected in the dirtiest environments. Drop tested to 4m and well protected from water ingress through IP65 and IP67 certification, T4x allows uninterrupted working in the most demanding environments.
Eliminates poisoning and cuts number of sensor replacements
Achieve more with less resources, T4x eliminates poisoning and cuts number of sensor replacements by 75% only 1 sensor needs replacing over the device’s lifetime.
Go to 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 more than 15 flammable gases at once straight out the box, as well as oxygen, and 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.
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 5 year warranty and RoHS lead free compliance saves you money and delivers on safety and environmental regulation.
