T4x is Crowcon’s Zone 0-approved personal protection solution for detecting the four most common gas hazards: carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion, offering you compliance and low cost of ownership in one simple-to-use solution.

The T4x has three sensor technology options for you to select according to your needs: Dual Toxic sensor for CO and H2S, Long-Life Oxygen (LLO2), and the MPS™ sensor, which has zero risk of device poisoning and can accurately identify over 15 different flammable gases in one device.

The large single button and intuitive menu system allows T4x to be operated wearing gloves with minimal training, and it is durable by design and includes an integrated rubber boot as standard, with all the durability you can expect from the T4 range. Plus, its 35+ hour battery life (double that of our original T4) allows multiple or longer shifts between recharging, allowing for uninterrupted working in the most demanding environments.
