Product Overview

Crowcon t4x Gas Detector

Single Gas & Multi-gas Detectors | Portable Gas Detection & Safety | Industrial Locations & Hazardous Area Zones

The T4x is a portable gas detector manufactured by Crowcon which provides a personal gas detection solution against four of the most common gas hazards – carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion. The T4x also now has improved detection of pentane, hexane and other long chain hydrocarbon.

Now with added industry leading sensor technologies to improve worker safety and cost you less over time.

This portable gas detector offers compliance, robustness and a low total cost of ownership. The large single button along with the intuitive menu system allows the Crowcon T4x to be operated easily with gloves on.

Crowcon T4x is the toughest portable gas detector – durable by design and includes an integrated rubber booster as standard.

The gas detector has been drop tested to 4m and is well protected against water ingress with IP65 and IP67 certification. The Crowcon T4x is also Zone 0 ATEX approved allowing for uninterrupted work in the most demanding environments.

T4x helps ensure compliance across site by eliminating the need to ensure each device is calibrated for the relevant flammable gas as it accurately detects more than 15 flammable gases, in any mix, at once, while being Type 1. Being poison resistant and with battery life doubled, operators are more likely to never be without a device. T4x reduces the 5 year total cost of ownership by over 25% and saves 12g of lead per detector which makes it easier to recycle at the end of its life, and better for the planet.

Key Features

  • 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
