  • Small and handy dose rate meter for the measurement of gamma radiation and X-rays.
  • Measurment: ambient dose equivalent rate.
  • Detector: energy compensated Geiger-Muller-tube.
  • Large, digital indication of measured values on LC-display (illuminable).
  • Selectable simultaneous or separate indication of dose and dose rate, additionally quasi-analog indication of dose rate (logarithmic bargraph).
  • 4 preset dose rate alarm thresholds.
  • 4 preset dose alarm thresholds.
  • Connectible acoustic single-pulse indication.
  • Automatic and continuous storage of the dose.
  • Storage of the dose and of set parameters even at batt change.
  • High reliability due to test functions and permanent self control.
  • Designed for rough use, housing made of aluminium, protection class IP54 (splash proof).
