Micro IV - The flexible Single-gas detector

Jun 02 2009

The Micro IV, from GfG Gesellschaft für Gerätebau mbH (Germany)  is the optimum solution for personal protection from toxic gases and vapours. It is very small and light, and a crocodile clip secures it safely on a belt or pocket. The housing is extremely shock and scratch resistant. Of course the Micro IV is approved for use in explosion endangered areas.

 

The plug-in sensors are pre-calibrated and can be replaced easily. The Micro IV recognizes the new sensor type, measuring gas, detection range, calibration curve as well as alarm threshold values. Only one minute after sensor replacement the Micro IV is ready for operation.

 

The Micro IV provides 3 programmable alarm thresholds for toxic gases. The warning occurs when the programmed values are exceeded. For toxic gases the Micro IV provides additional alarms for exceeded STEL or TWA values. The audible alarm (95 dB(A)) of the Micro IV is noticeable even in noisy environments. The sound frequency changes to avoid confusion with machine noise. The three alarm levels can be distinguished by different frequencies. Two extremely bright flashing LEDs indicate gas alarm. The alarm levels are distinguished by different flashing frequencies.

 

The data logger saves up to 200 events. Alarm thresholds A1, A2, A3 as well as STEL and TWA are stored together with time and gas concentration. Data is stored continuously, old data is overwritten.

 

The Micro IV provides an infrared interface for data transfer via PC, the data interface, for quick device configuration or via dockingstation, which allows execution of the daily bump test as well as calibration / adjustment automatically in a very short time.

 

For monitoring gases in manholes, sewers, rooms and containers before entering, a motorised pump can be attached easily. The high performance pump takes samples over long distances and is activated by a single button. The pump has its own, autonomous power supply and does not affect the run time of the Micro IV.

 

The Micro IV measures and monitors gases continuously for up to 9 months using only one alkaline battery. The battery can be replaced easily. After battery replacement the MICRO IV is immediately ready for operation. The Micro IV indicates the battery capacity; insufficient battery capacity triggers a “low-battery“ alarm.

 

When configuring the Micro IV a confidence beep can be activated. The dockingstation allows quick and easy configuration of the Micro IV.

 

The Micro IV detects a wide range of toxic gases, hydrogen and oxygen by means of electrochemical sensors – you can see the Micro IV at Achema on GfG’s stand (Hall 4.1, Stands N20-N22)
