Crowcon Tetra T3 Multi Gas Detector

Code: TETRA T3

Simple operation
Calibration due warning
Can be submerged in water

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
