Description
The Crowcon T4 is a portable gas detector, suitable for detecting the 4 most common gas hazards:
Carbon Monoxide (CO)
Hydrogen Sulphide (H2S)
Flammable Gases
Oxygen Depletion (O2)
The Crowcon T4 offers compliance, robustness and low cost of ownership in a simple to use solution. The T4 comes with a large single button and intuitive menu system which allows it to be operated while wearing gloves and with minimal training.
The T4 is one of Crowcon’s toughest portables, 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. The Crowcon T4 is drop tested to 4m and well protected from water ingress through IP65 and IP67 certification.
