| | | Small, light and robust The MICRO III Is an extremely small Instrument compared to other detectors. With Its dimensions of only 47 x 88 x 25 mm (WxHxD), It weighs only 61 grams and can comfortably fit Into a shirt pocket. A built-in clip secures the MICRO III safely to a belt or pocket. The casing Is extremely shock and scratch resistant. The protection type IP 56 Indicates that the Instrument Is sealed against dust and water. The MICRO III uses the AQUA-SHIELD (accessory sensor Inlet) which ensures that the monitor will provide excellent performance In harsh conditions. More protection through easier operation The G 201 and the G 202 Is produced without buttons or switches. Therefore an operating error Is completely eliminated and time consuming training Is reduced. The plug-in smart sensor can be easily replaced. The MICRO III recognizes the new sensor type, another measuring gas, detection range, calibration curve, as well as alarm threshold values. Numerous features The MICRO III comes standard with many features including automatic zeroing, Auto-Cal | | calibration, confidence bleep, battery check, and three factory set alarm points. The following models are available: G201 with loud alarm horn and bright alarm lamp G202/G212 as G 201, additional: display for gas concentration, battery capacity and service control G203/G213 as G 202, additional: Peak/ minimum calibration, TWA/STEL, control keys for display light and service functions. All MICRO III devices feature audible or a visible confidence signal. Zero point adjustments can be carried out quickly and easily In fresh air. Attachable pump An electrical high-performance pump will take samples of gases from mines or tanks. The pump replaces the battery cover and is a fixed part of the instrument with its own power supply. The operation of the pump will have no influence on the operation time of the MICRO III. Loud audible alarm The audible alarm of the MICRO III has a changing frequency. Machinery noises do not interfere with the horn signal, like in the case | | |
