LUDLUM 193-6 Extended Reach Gamma Survey Meter (10 µSv/h (1000 µR/hr))

Application: Low level (microR) gamma survey

Detector (D x L): EJ-212 plastic scintillator, 15.2 x 2.5 cm (6 x 1 in.) 

Sensitivity (137Cs gamma): Typically 150 kcpm per μSv/h (1500 cpm per µR/hr) 

Energy Response: Energy dependent

Linearity: Reading ± 10% of true value

Meter Dial: 0 - 1 µR/hr, BAT TEST

(others available)

Detector Range: Background to 10 µSv/h (1000 µR/hr)

Alarms: 

Fixed: Alarm point that can be set at any point from 10% of full scale to full scale. Indicated by a constant audible tone, and the lamp turning on.

Deviation: A quick alarm that is based on background radiation levels. When the instrument is turned on, it takes an eight-second measurement of background radiation levels and determines a deviation alarm setting. If the radiation level exceeds this setting, the alarm audio will beep every 1/8 second, and the lamp will flash.

Power: Two standard alkaline ˝D˝ cell batteries

Battery Life: Typically 600 hours with alkaline batteries (battery condition can be checked on meter)

Construction: Cast and drawn aluminum with beige powder coat

Overall Length: 1.3 m (51 in.)

Weight: 3.9 kg (8.5 lb), including batteries
