The Crowcon T4 (Tetra 4) portable gas detector is the ultimate solution that combines compliance and robustness at a low cost. Its built-in gas sensors are incredibly sensitive, capable of measuring in Part Per Billion (PPB), providing protection against the four most common gas hazards, which are:

  • Carbon Monoxide (CO)
  • Hydrogen Sulphide (H2S),
  • Flammable Gases (LEL)
  • Oxygen Depletion (02).

 

With its single button operation and intuitive menu system, the T4 ensures easy use even when wearing gloves. This product requires minimal training for use. It is the toughest portable gas monitor from Crowcon to date, designed to withstand the harshest conditions. The integrated rubber boot adds to its durability, making it a reliable companion.

The Crowcon T4 has undergone rigorous testing, including drop tests from a height of 4m. This product is certified with IP65 and IP67 ratings for protection against water ingress. This means it can be used without interruption in demanding environments.

Features of the Crowcon T4

 

TWA Resume

In addition to its ruggedness, the T4 offers several useful features. The TWA Resume feature accurately calculates the time-weighted average (TWA) toxic gas exposure over an entire work shift, even if the T4 is turned off during breaks or travel. The TWA Resume function provides the option to include previous measurements from within the correct time frame.

18 Hour Battery Life

With an impressive 18-hour battery life, the T4 ensures longer shifts between recharges. Its traffic light indicator provides constant visual assurance of its operation, meeting all bump-test and calibration policies.

Accessories

The Crowcon T4 also comes with accessories such as a belt clip, lanyard, and carrying case, making it convenient to carry and use.

With its versatility across various heavy and hazardous industry sectors, the T4 has established itself as an indispensable tool for personal protection against gas and chemical exposure.
