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).

Key Features

  • Expanded Gases: Ammonia, Ozone, Sulphur Dioxide, H2 filtered CO (for steel plants) and IR carbon dioxide (for safe area use only)
  • Top mounted, backlit display of all gas readings, diagnostics and battery life
  • Rapid and effective warning with a 95 dBa audible alarm, an extremely bright red/blue visual alarm and vibrating alarm as standard
  • Water and Dust resistant to IP67, can be submerged in water
  • Reliable Lithium-ion battery provides over 16 hours continuous operation from a single charge with no memory effects
  • Rugged impact resistant design provides extra shock and vibration protection
  • Single button operation for all functions, can be operated with gloved hands
  • Standard Gases: CH4 (Methane), H2S (Hydrogen Sulphide), CO (Carbon Monoxide) and O2 (Oxygen)
  • Up to 4 gases in a small and lightweight design
