Crowcon Tetra 3 Multigas Personal Monitor - CH4, O2 & CO (0-500ppm)
A compact personal gas detector, the Crowcon Tetra 3 is perfect for clipping straight onto your clothes and will constantly monitor the air around you for methane (CH4), oxygen (O2) and CO (carbon monoxide).
When gas content is detected the Tetra 3 shows a reading on its top-mounted backlit display (which can be seen simply by looking down when it's clipped to your clothes) and will also make sure you know about gas content quickly by using an extremely loud, 95dB audible indicator, vibration feedback and bright flashing dual colour LED light indicator.
Crowcon's Tetra 3 is also ATEX certified, making it suitable for use in potentially combustible environments. Please see the tech specs box below for more information on this product's ATEX directive and also make sure that the environment you're entering is suitable before use.
