T4 integrates innovative safety features and an intuitive, rugged design to provide advanced protection for those working in harsh environments. This portable multigas detector, which is exceptionally easy to use and service, protects against the four most prevalent gas hazards: carbon monoxide (CO), hydrogen sulfide (H2S), flammable gases, and oxygen (O2) depletion.
Offers you compliance, robustness, and low cost of ownership in a simple to use solution. The large single button and intuitive menu system allow T4 to be operated wearing gloves with minimal training. Crowcon's toughest portable yet, 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.
TWA Resume
Unique to 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 work shift, ignoring all previous measurements. The TWA Resume function, however, provides the option to include previous measurements from within the correct time frame.
