Personal Multi-gas monitor

Published:  01 April, 2006

Extending the family of Tetra portable gas monitors, the lightweight Tetra:3 from Crowcon Detection Instruments combines extremely rugged design with small size and simple operation.

Designed for use in demanding industrial environments, including confined space work in the construction industry, the Tetra:3 has simple, single button operation which can be used with a gloved hand. Monitoring oxygen, toxic and flammable gases, the unit has a top mounted, backlit display showing all gas readings, diagnostics and battery life.
Despite its compact size and low weight (less than 300g), the Tetra:3 is very rugged. Its shatterproof housing with rubber over-moulding, provides extra shock and vibration protection, and giving it water and dust resistance to IP67.
If a hazard is detected, Tetra:3 gives rapid and effective warning with a powerful 95 dBA audible alarm, an extremely bright red/blue LED visual warning, and by vibrating. There are two levels of alarm, which can be set to have distinctive tones.
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 Tetra:3 comes standard with a stainless steel alligator pocket clip and an optional harness for chest mounting.
