4-Gas detector

The 4-gas detector Microtector II G450 has been specifically developed for meeting the requirements of daily work. It reliably detects and warns of gas hazards of O2, H2S, CO and of all combustible gases, is part of the personal protection equipment and can be carried directly on the protective clothing without hindering efficient work. The robust and durable GfG high performance sensors are able to measure the smallest gas concentration and thus to monitor the lowest occupational exposure limit value.

The innovative multi-gas detector G450 passes the performance test and is certified according to EN 60079-29-1 (explosive gases), EN 50104 (oxygen) and EN 45544 (toxic gases).

Optical and acoustical alarm

An innovative alarm system has been developed to reliably warn of possible gas hazards. In case of gas hazard, the display changes its colour – depending on the hazard level – like a traffic light to green, orange or red. In addition, circumferential LED lights flash with the respective colour. A high performance audible alarm is also in noisy environments louder than any other ambient noise. The big coloured graphic display is reversible by 180° such that an easy reading is assured even when wearing the device on the body. The integrated zoom function can be used to enlarge the display at a push of a button. This ensures an easy reading of the measurement values even in difficult situations and both hands are kept free.

Designed for daily use

The Microtector II G450 has a robust casing. Due to the high-class rubber coating, the device is extremely shockproof and water resistant (IP67). The operating time is up to 30 hours such that its usage for the entire working days can be assured. For power supply, either batteries or rechargeable batteries can be used. The gas detector Microtector II G450 is particularly small and the the lightest device in its class. Due to this, users consider wearing the device as particularly convenient and non-disturbing.

Awarded functionality

The innovative design and exceptional functionality of this device were honoured with one of the internationally most coveted prized for product design, the red dot design award.

Rechargeable or non-rechargeable batteries

Rechargeable NiMH or alkaline batteries which can be exchanged quickly and easily are available for providing the power supply. Their operating time is up to 30 hours. In combination with the NiMH battery pack equipped with EX-protected LED lights, the device can additionally be used as a bright flash light. With the help of the charging tray, the battery packs can be charged comfortably. However, charging is also possible using the docking station, test station or the vehicle charging cable for 12 V and 24 V.

Electrical pump for release measurement

Apart from operation in normal diffusion mode, the gas detector can optionally be equipped with the electrical pump G400-MP2. The pump has an own power supply, flow monitoring and communicates with the gas detector.

Maintenance: cost-saving, fast and easy

Whether it’s a simple functional test or a complete documentation, tried and tested solutions are at your disposal. The mobile test station TS400 and automatic test and calibrating station DS400 are the ideal supplements to save money, time and efforts. Fast reacting GfG high performance sensors and a sophisticated pump system enable the lowest gas consumption.
