Single Gas Detector

We offer high quality toxic gas detector for detecting various types of gases, including hydrogen sulfide, carbon monoxide, combustible gases and more. Based on latest technology, toxic gas detectors are quality and sensitivity and their ability to perform comprehensive testing and detection. All the instruments in our range of toxic gas detector is specifically designed to deliver you with the utmost in precision and reliability. We provide various kinds of toxic gas detector and gas detecting system like toxic gas detector, toxic gas detection system, hydrogen sulfide detectors, hydrogen sulfide gas detectors, multi gas detector, multi gas leak detector and toxic gas monitor.
Micro III / IV
  • The MICRO IV is the state of the art derivative of the well known
    single gas detector
  • MICRO III. Besides its simple operation and reliable warning the
    flexible device convinces because of its large memory, an IR
    interface and the revolutionary docking station.
The event memory saves all important data
  • When was alarm triggered? (time)
  • Which alarm was triggered? (A1, A2, A3, TWA, STEL value)
  • Which gas concentration was present?
  • Bright optical alarm and loud horn (95 dB)
  • Recording event data, TWA and STEL values in data logger
  • Infrared interface for data transfer to the docking station
  • Quick calibration and function test by docking station
  • Up to 6 months continuous operation (24 h/day) with one
  • For toxic gases, Oxygen and Hydrogen
  • ATEX : II 2G, EEx ib IIC T3/T4
  • Option : plug on sampling pump
The MICRO IV docking station is a trendsetting device management system, which enormously reduces cost of ownership and duration of the calibration. The docking station checks the acoustic and optical alarm functions, device errors, alarm thresholds and response times of the MICRO IV. The bump-test comprises :
  • Response time
  • Alarm thresholds
  • Alarms (optical and acoustic)
  • Device software
  • Device- and software identification
  • Device errors
Up to 6 MICRO IV can be checked for utilizability (bump-test) and be calibrated simultaneously. Simplest operationThe docking station reduces the daily time involved for calibration and function test (bump test) dramatically. Already few calibrations and function checks annually reduce the cost of ownership considerably.

The uncomplicated and quick operation in connection with the self-describing traffic lights signals prevent from user mistakes.

  • Red = failure
  • Gelb = test running
  • Grün = device ok!
Due to the compact size the station can be placed almost everywhere without any problems. No further modules or master stations are necessary.
