  • DETECTOR: various detectors, view the datasheet (peo_pdf_logo2)
  • ALARMS: count rate, exposure/dose, and scaler alarm setpoints adjustable over the display range
  • OVERLOAD: high count rate saturation protection prevents false display of lower count rates
  • LOSS OF COUNT ALARM PROTECTION: after preselected time interval (default 60 seconds) of no pulses from detector, audible and visual alarms will be activated
  • DISPLAY RANGE: 0.0 cps to 99.9 kcps; 0.00 cpm to 999 kcpm; 0.00 Bq to 99.9 kBq; 0.00 dpm to 999 kdpm; 0.00 μR/h to 999 R/h;
  • μSv/h to 999 Sv/h
  • BACKLIGHT: built-in ambient light sensor automatically activates low-power LED backlight
    • MODE – alternates between NORMAL (count rate), MAX (captures peak rate), and COUNT (user-selectable preset count time from 0 to 10 minutes)
    • AUDIO – turn “click” audio On/Off
    • UNITS – changes the units between count rate (cpm, cps), dose/exposure (μSv/h, mR/h), or disintegration (dpm, Bq)
  • RESPONSE TIME: user-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
  • BATTERY LIFE: approximately 750 hours
