Residual oxygen meter GMH 3692 GOG-L - for low oxygen concentrations

The hand-held measuring instrument GMH 3692 GOG-L detects reliably the residual oxygen concentration. It consists of the air oxygen meter GMH 3692 (1), a hand pump and an oxygen sensor with penetration needle (3).


Features (oxygen meter GMH 3692-L):

  • Double display for oxygen and temperature
  • Measured units: O2-concentration and O2-partial pressure
  • Alarm detector with integrated horn
  • Automatic temperature compensation
  • Min-/max-value memory, hold function
  • Serial interface, can be connected to RS232 or USB interface of a PC
  • Connectable to bus system (up to 5 devices can be connected to one PC interface)
  • Battery and d.c. operation possible
  • Operating control: 6 membran keys for ON/OFF switch, selection of measurement range, min- and max- value memory, hold-function, calibration etc.
  • Calibration:
    • 1-point-calibration: simple quick calibration in atmospheric air (press button to compensate unit to 20,9%).
    • 2-point-calibration: first point at atmospheric air (20,9%), second point freely selectable
