Open: 12.26 cm2 (1.9 in2)
Efficiency:
Alpha
239Pu: 11%
Beta
99Tc: 14%
32P: 32%
14C: 2%
90Sr/90Y: 22%
125I: 0.2%
Gamma
5.5 cps per μSv/hr (3300 cpm per mR/hr) (137Cs)
99mTc : ≤ 1%
Display: 3½ digit LCD with large 12.7 mm (0.5 in.) digits, low-battery indicator, MAX, ALARM
Units: (k)cps, (k)cpm, (k)dpm, (k)Bq, mR/hr, µSv/h
Range:
0.00 cps to 19.9 kcps
0 cpm to 999 kcpm
0.00 Bq to 19.9 kBq
0 dpm to 999 kdpm
0.00 to 500 mR/h
0.00 to 1999 µSv/h
Linearity: ±10%
Backlight: Built-in ambient light sensor automatically activates low-power LED backlight, or may be configured for 'Continuous On' (will reduce battery life)
Controls
ON / OFF / QUIET: Press to turn ON; Tap to alternate between click audio and QUIET; Hold for OFF
MODE: Alternates between RATE (count rate), MAX (captures peak rate), and COUNT (preset count time from 0 to 20 min.)
UNITS: Changes units between count rate (cpm, cps), dose/exposure (µSv/h, mR/hr), or activity (dpm, Bq)
Response Time: User-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
Resolving Time: Approximately 110 µs as defined by IEC 60325
Alarms: Count rate and scaler alarm setpoints adjustable over the display range
Overload Protection: High rate saturation protection, indicated by flashing display and audio alarm, prevents false display of lower count rates
Loss of Count Protection: After 60 seconds of no pulses from detector, unit will flash a zero reading and the alarm audio will be triggered
Click Audio: Greater than 60 dB at 0.6 m (2 ft)
HV Testpoint: Accessible by removing battery cover, allows HV measurement and pulse injection for calibration using optional cable (PN: 8303-1044)
