LUDLUM 3000 Digital Survey Meter (0.0 cps ~ 99.9 kcps)

Compatible Detectors: GM, scintillation, or proportional

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

Units: (k)cps, (k)cpm, (k)Bq, (k)dpm, (µ)(m)R(/h), (µ)(m)Sv(/h).

Indicators: bar graph, 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

0.00 µR/h to 999 R/h

0.00 µSv/h to 999 Sv/h

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: Readings within 10% of true value

Data Logging: Can store up to 1000 data points internally. Requires Lumic Data Logger Kit, see Options.

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

Alarms: Two 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 the display and an audio warning will be triggered.

High Voltage: 400 to 1500 Vdc
