Crowcon Tetra 3 Gas Detector
Features and Benefits
Crowcon T4 Gas Detector (LEL, H2S, CO, O2) offers you compliance, robustness and low cost of ownership in a simple to use solution. The large single button and intuitive menu system allows Crowcon T4 to be operated wearing gloves with minimal training. Crowcon’s T4 is toughest portable device which is durable by design and includes an integrated rubber boot as standard. It also has an optional clip-on filter cover, which can be easily removed and replaced ensuring that 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. It is available now with improved detection of pentane, hexane and other long chain hydrocarbons.
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 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. With a battery life of 18 hours, T4 Multi Gas Detector allows multiple or longer shifts to be worked between recharging. Crowcon’s visual ‘traffic light’ indication, provides constant visual assurance that 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.
