LUDLUM 3002 Alpha-Beta Digital Survey Meter (0.0 cps ~ 99.9 kcps)

Compatible Detectors: alpha-beta scintillation or gas proportional

Display: 3-digit auto-ranging LCD with large 20 mm (0.8 in.) digits.

Units: (k)cps, (k)cpm, (k)Bq, (k)dpm.

Indicators: bar graph, radiation type (alpha (α), beta(β)), MAX, ALARM, USB, audio, low-battery

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

Operational display ranges are dependent on the detector and dead time configuration. The minimum and maximum display can be set to limit the display to the calibrated range.

Linearity: Within 10% of true value

Response Time: User-selectable from 1 to 60 seconds, or auto-response rate FAST or SLOW

Alarms: Two adjustable count rate, exposure/dose, and count alarm setpoints adjustable over the display range

Overload Protection: High count rate saturation protection prevents false display of lower count rates. "OL" will appear on display and an audio warning will be triggered.
