Frequently bought together:


The Microtector II G450 was specifically developed for personal protection against gas dangers. Its sturdy design allows it to be used in a variety of applications, from the steel industry or refineries to sewer construction or the fire deparment. The compact multi-gas detector monitors up to four gases simultaneously. To reliably fulfill this purpose, the G450 is equipped with a catalytic combustion sensor for combustible gases and vapors (0 to 100 % LEL) and three electrochemical sensors for toxic gases or oxygen.

The Microtector II G450 simultaneously monitors four gases such as methane, carbon monoxide, hydrogen sulfide and oxygen. Our selection of different long-life sensors makes the multi-gas detector a reliable and versatile companion for daily work in environments with potential gas dangers. We also offer an optional electric pump which can be attached to clear confined spaces from a safe distance.

Safety and operation
The Microtector II G450 is certified for use up to Ex zone 1. It is also protected against the ingress of water and dust according to protection class IP67, making the 4-gas detection device suitable for demanding applications. The housing made of rubberized polycarbonate protects the device from shocks and vibrations. Its award-winning design, low weight and the convenient crocodile clip ensure high wearing comfort. The device is operated using only three buttons and the color-backlit display. For better usability, the screen can be rotated by 180 degrees if the situation requires it. An optional battery module with an explosion-proof flashlight is also available for low-light conditions.
