Collection: GFG Portable Gas Detectors

The Microtector II G460 has been specially developed 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 seven gases simultaneously. For this purpose, the G460 is equipped with a heat tone sensor for combustible gases and vapours (0 to 100 % LEL), an infrared sensor (NDIR) and 3 electrochemical sensors for toxic gases as well as oxygen. In addition, a PID sensor for volatile organic compounds (VOCs) can be used instead of one of the EC sensors.

The Microtector II G460 simultaneously controls seven gases such as methane, propane, carbon monoxide, carbon dioxide, hydrogen sulphide, hydrogen and VOCs. The selection of different long-life sensors makes the multi-gas detector a versatile and reliable 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 G460 is certified for use up to Ex zone 1 and in hazardous areas in mining (M1). In addition, it is water- and dust-protected according to protection class IP67, making the 7-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 by 180 degrees if required. An optional battery module with explosion-proof torch is available for low-light conditions.

Alarm and battery life
In the event of a threshold being exceeded, the G460 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 G460 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.

The Micro IV is part of the personal protective equipment of firefighters and workers in mines, steelworks, refineries and canal construction. Thanks to its compact design and long operating time, it is a reliable 1-gas detector even for difficult conditions. The Micro IV monitors toxic gases, oxygen or hydrogen and alerts its wearer visually and acoustically. The data stored in the data logger can be read out conveniently via the infrared interface or a docking station.

The Micro IV has a slot for an electrochemical sensor. Smart Sensor technology allows for quick and easy sensor replacement. A wide range of EC sensors is available for a variety of toxic gases, hydrogen as well as oxygen with different measuring ranges such as ppm and vol.-%. This makes the Micro IV suitable for monitoring gas dangers such as ammonia, carbon monoxide, hydrogen sulphide, nitrogen and a lack or excess of oxygen. Optionally, an electric pump can be connected to safely clear confined spaces and containers.

The TeamLink G999L is a portable connected safety monitor for securing up to 10 personal gas detection devices of the G999 and G888 series by radio. Its compact and robust design, ease of use and range of up to 700 metres in free field make the TeamLink the ideal addition for response teams such as fire brigades or service and repair teams working with portable gas detectors in potentially dangerous areas.

Portable gas detection devices are first of all intended to warn their wearer and people in the immediate vicinity of dangerous gas concentrations. However, this alone is not enough. Information about an alarm and its cause must be available to the supervising person, i.e. the team leader, squad leader or the second man of a buddy system. This is the only way to warn other team members in an emergency and to initiate measures without the rescuers putting themselves in danger or wasting too much time on self-protection against unknown dangers.

Keeping the team safely in sight
The supervising person can see the status of the individual team members at a glance on the TeamLink and can switch through the local readings. If all LEDs light up green, all team members are safe. In the event of an alarm, the display changes to red for the corresponding team member, and to yellow in the event of connection problems. In addition to an automatic alarm caused by a local gas dangers, there is the possibility of a man-down alarm (motionlessness) as well as a panic alarm (active call for help).

Safety and operation
The TeamLink is certified for use up to Ex zone 1 and is water- and dust-protected in accordance with protection class IP67, making the Connected Safety Monitor suitable for challenging applications. The rubberised polycarbonate housing offers excellent protection against shocks and vibrations. The practical design and the robust crocodile clip ensure optimum wearing comfort. Intuitive operation is via three buttons and the colour backlit display.

Accessories
The TeamLink battery can be charged with the smart charging cradle DIC 888/999. The G888/G999 Visual software is the ideal complement to the portable TeamLink. It displays measured values and status of teams with more than 10 portable gas detection devices of the Polytector III G999 and Microtector III G888 series on a PC or laptop with optional USB wireless dongle. A complete overview of the accessories and all extensions offered for the TeamLink can be found at the bottom of this page.
