LUDLUM 19A MicroR Survey Meter With Alarm (0 ~ 5 µSv/h)

Application: Low-level (μR) gamma survey

Detector (D x L): NaI(Tl) scintillator, 2.5 x 2.5 cm (1 x 1 in.)

Detection Range: Background to 500 µR/hr

Sensitivity (137Cs gamma): Approximately 17,500 cpm per μSv/h (175 cpm per μR/hr)

Energy Response: Energy dependent (see Energy Response Curve)

Linearity: Reading ± 10% of true value
