Crowcon Tetra 3 Personal Multi-gas Monitor
The Tetra 3 multi-gas monitor is the newest addition to the Tetra family. Tetra:3's single button operation, small size and weight make it the easiest to use gas detector on the market.
Based on the proven and highly successful Tetra product, Tetra:3 is designed for use in demanding industrial environments. Despite it's compact size the Tetra:3 is ultra-rugged and water proof.
Gases include the most common four (carbon monoxide, methane, oxygen and hydrogen sulphide), but also an expanded range: ammonia, ozone, sulphur dioxide, H2 filtered CO (for steel plants) and IR carbon dioxide (for safe area use only).
