TETRA 3
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.
Gdzie kupićThe Tetra 3 portable multi gas monitor can detect and monitor the four most common gases (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).
This ultra-robust design provides impact, water and dust resistance, as well as extra shock and vibration protection to withstand even the harshest environments.
The Tetra 3 is super user-friendly, with a single button operation for all functions which can be used with gloved hands, plus a top mounted backlit display of all gas readings, diagnostics and battery life make it simple and intuitive to use, minimising training needs.
With clear audio-visual and vibrating alarms, you can be confident there will be no missed signals when warnings are issued, enabling prompt evacuations from hazard zones when it matters.
