Crowcon Expands Capabilities of its Lightweight, Intrinsically Safe T3 Portable Multi-Gas Detector
Gas detection specialist Crowcon has expanded the capabilities of its highly successful 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 new 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.


Is this a data logging device and is there an option for hydrogen compensated carbon monoxide sensor.
Dear Carl
Thanks for your question.
Yes the T3 unit has an extensive Data (3000 logs i.e. 50 hours at 1 minute intervals) and Event (>1500 individual records) log capability that is viewable via Portables PC software, offering users the ability to download, interrogate and save log files. The T3 is not yet available with a hydrogen compensated sensor, however we do currently have units in test with a view to offering this capability in the near future.
