Crowcon Tetra 3 Multigas Personal Monitor - CH4, O2 (3yr) & H2S
Don't take risks in the workplace when gas is involved; with the Crowcon Tetra 3, users can be instantly alerted to the presence of hydrogen sulphide (HS2), oxygen content (O2) and methane gas (CH4).
Made for personal use, the Tetra 3 is small and lightweight enough to be carried comfortably or alternatively can be worn completely hands-free on your clothing thanks to the included clip. When attached to clothing it's easy to get a reading of gas content thanks to the innovative top-integrated LCD screen (just look down to see a reading without taking the meter off your clothes!).
Ultra rugged and protected from water damage thanks to IP67 rating (it can even be submerged in water) the Crowcon Tetra 3 is also ATEX designated for use in hazardous environments. Make sure you check before use that the environment you're entering is suitable for use with the Tetra 3 (more information about ATEX certification is available in the tech specs box below).
When one of the three gasses is detected the Crowcon Tetra 3 will both provide a reading of the concentration and will also alert the user to the gasses' presence. This gas detector features three separate alerts that will all work simultaneously and uses vibration feedback, bright LED lights and a loud, 95dB audible tone to make sure it gets the users' attention.
