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
Southern Water buys 800th gas detector!
Southern Water (UK) has recently purchased its 800th Tetra portable gas detector from Crowcon, mainly for use by staff working in confined spaces with sewerage processes
Despite its compact size and low weight of around 500g, Tetra is very rugged.
The shatterproof plastic housing is over-moulded with rubber and incorporates a flexible internal architecture to resist shock and vibration.
The unit is water- and dust-resistant to IP65, floats in water and is ATEX approved for use in hazardous areas.
If a hazard is detected, Tetra gives rapid and effective warning of the presence of gas.
The user is alerted by extremely bright blue and red LED beacons and a powerful 90 dBA alarm.
Alarm tones are adjustable to ensure easy discrimination from noisy machinery.
An integral vibrating alarm is also a standard feature.
Tetra is easily customised for different applications: intelligent, user-changeable sensors for a wide range of gases are pre-calibrated to allow "plug and play" operation.
Sensors are available for oxygen, flammable gas and a full range of toxic gases, including all hazards commonly encountered in confined spaces.
Two versions of the instrument are available: a rechargeable unit using lithium-ion batteries for 12 hours operation from one charge, and a version powered by three conventional AA alkaline batteries.
For testing confined spaces prior to entry, Tetra can be specified with an optional built-in electric sampling pump or used with a separate manual aspirator. Request a free brochure from Crowcon Detection Instruments ...
