Tetra 3 Multigas Personal Monitor with Charger by Crowcon

The Tetra:3 multi-gas monitor is a compact, robust and easy to use diffusion based detector.

Single button operation, small size and clear top-mounted display make it a favourite in the market amongst those working in demanding industrial environments such as those in the water, telecoms, food, brewing or hydrocarbons sectors.

Despite its compact size the Tetra:3 is ultra-rugged and water proof.

  • Up to 4 gases in a small and lightweight design
  • Infra-red carbon dixoide sensor version for safe area use (ie non-explosion risk areas)
  • Single button operation for all functions, can be operated with gloved hands
  • Rugged impact resistant design provides extra shock and vibration protection
  • Reliable Lithium-ion battery provides over 16 hours continuous operation from a single charge with no memory effects.
  • Water and Dust resistant to IP67, can be submerged in water
  • Rapid and effective warning with a 95 dBa audible alarm, an extremely bright red/blue visual alarm and vibrating alarm as standard.
  • Top mounted, backlit display of all gas readings, diagnostics and battery life.

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).
