The Tetra 3 multi-gas monitor is a compact, robust, easy-to-use diffusion-based detector. Its single-button operation, small size, and clear top-mounted display make it a popular choice for those working in challenging industrial environments such as water, telecommunications, food processing, brewing, and hydrocarbon sectors.

The Tetra 3 portable multi-gas monitor can detect and monitor four commonly found gases – carbon monoxide, methane, oxygen and hydrogen sulphide. It can also detect an expanded range of gases, including ammonia, ozone, sulphur dioxide, H2-filtered CO (specifically for use in steel plants), and IR carbon dioxide (safe area use only).

Robust

  • Rugged And Impact-Resistant Design Provides Extra Shock And Vibration Protection – protects the harshest environment.
  • Water And Dust Resistant to IP65 and IP67.

Effective Warning

  • 95dB Audible Alarm – ensures clear warning, facilitating prompt evacuations from hazard zones.
  • Vivid Red/Blue Visual Alarm.
  • Vibrating Alarm.

Reliable

  • Proven Sensor Technology And Software Operation – Provides reliability you can trust and has the power to cover you for an extended shift.
  • Lithium-ion battery Provides Over 14 Hours of Continuous Operation From A Single Charge With No Memory Effects.

User friendly

  • Single Button Operation For All Functions – can be operated with gloved hands.
  • Top Mounted, Backlit Display Of All Gas Readings, Diagnostics And Battery Life – ‘at a glance’ operating status.

Gases and Ranges

Ranges and alarms vary by country and application; these can be configured as required. Each channel can have two instantaneous alarms. Toxic channels also have TWA alarms. Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and ethylene as standard.
