Intrinsically safe portable multi-gas detector

03 March 2010

Crowcon has expanded the capabilities of its Tetra:3 (T3) personal multi-gas detector with three more toxic gas sensors: ozone (O3), sulphur dioxide (SO2) and ammonia (NH3). This complements the existing sensor range which includes flammable gases, oxygen (O2), hydrogen sulphide (H2S), and carbon monoxide (CO).

The sensors widen the applications for the T3 to include the chemical, pharmaceutical, food and beverage processing industries, as well as water and wastewater treatment facilities.

Featuring a top-mount display and the capacity to detect up to four gases at once, the T3 is designed for use in the most demanding industrial environments, including confined space work. It features intuitive, single button operation, essential for users with gloved hands.

If a hazard is detected, the T3 gives rapid and effective warning with a powerful 95 dBA audible alarm, an extremely bright red/blue LED visual warning, and by vibrating. Despite its compact size and low weight (less than 300g), the T3 is very rugged. It has a shatterproof housing with rubber over-moulding, providing extra shock and vibration protection and giving it water and dust resistance to IP67.

A lithium-ion battery provides over 18 hours continuous operation from a single charge, and there is a 30 day countdown warning of the calibration due date. The T3 is provided with a stainless steel alligator pocket clip as standard and has an optional harness for chest mounting.

To coincide with the expanded T3 gas sensor range, Crowcon has also launched a new 'universal charger', developed in response to the market need for reliable vehicle charging of detectors used by service and maintenance crews in the field. This latest addition firmly supports the T3 in a mountable cradle, offering a quick and easy storage solution as well as dependable charging with status indication.
