Product Description


The Crowcon T4 portable multigas detector provides effective protection against 4 common gas hazards: carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion. Now with improved detection of pentane, hexane and other long-chain hydrocarbons.

Top 3 Features & Benefits

1. Crowcon's Toughest Portable Gas Detector

The T4 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, T4 allows uninterrupted working in the most demanding environments.

2. TWA Resume Accurately Calculates Personal Exposure

If you have a responsibility relating to health & safety, take note of this unique feature specific to the T4. The TWA Resume function ensures toxic gas exposure is calculated accurately over an entire shift, even if T4 is switched off for a break or during travel to another site.

When most portable detectors are turned off, the algorithm that assesses TWA exposure assumes that it’s the end of the shift. When turned on again, these detectors act as if it is a new work shift, ignoring all previous measurements. The TWA Resume function, however, provides the option to include previous measurements from within the correct time frame.

3. Positive Safety Means You're Good to Go

When using the T4, Crowcon's +ve visual 'traffic light' indication, provides constant visual assurance that the T4 is operating soundly and conforms to site bump test & calibration policy. The bright green and red Positive Safety LEDs are visible to all and offer a quick, simple and comprehensive indication of monitor status to both the user and others around them.
