Microtector II G450
The Microtector II G450 is specifically designed for personal protection against gas dangers. The robust design allows it to be used in a wide range of applications such as the steel industry, refineries, sewer, construction and fire brigades. The compact multi-gas detector monitors up to four gases simultaneously. For this purpose, the G450 is equipped with a heat tone sensor for combustible gases and vapors (0 to 100 % LEL) and 3 electrochemical sensors for toxic gases as well as oxygen.
The Microtector II G450 simultaneously controls four gases such as methane, carbon monoxide, hydrogen sulphide and oxygen. The selection of different long-life sensors makes the multi-gas detector a reliable and versatile companion for daily work in environments with expected gas dangers. An optional electric pump can also be connected to clear confined spaces and containers from a safe distance.
Safety and operation
The Microtector II G450 is certified for use up to Ex zone 1. It is also waterproof and dustproof according to protection class IP67, making the 4 gas detection device suitable for demanding applications. The housing made of rubberised polycarbonate protects the device from shocks and vibrations. Award-winning design, low weight and the crocodile clip ensure optimum wearing comfort. The device is operated via three buttons and the colour backlit display, of which the display can be zoomed and rotated 180 degrees if required. An optional battery module with an explosion-proof torch is available for low-light conditions.

Alarm and battery life
In the event of a threshold being exceeded, the G450 warns its wearer in three ways: by light signal, vibration (optional) and loud horn (103 db(A)). The operating time is up to 170 hours, depending on whether a NiMH battery module or an alkaline battery module is used, and depending on the operating mode and the sensor equipment. The optional pump has its own power supply and therefore does not shorten the unit runtime. With a suction distance of up to 100 metres, continuous pump operation of up to 10 hours is possible.
Accessories
The DS400 docking station can be used to charge, calibrate and adjust the G450 multi-gas detector. The G400-MP2 smart pump can be plugged in for free measurement. In addition to charging and calibrating, the smart charger cap allows the data logger recordings to be transferred to the PC.
