Number of sources up to 5 up to 6
Air kerma rate 0.25 µGy/h – 350 mGy/h 0.36 µGy/h – 50 Gy/h
Exposure dose rate 30 µR/h – 40 R/h 40 µR/h – 5400 R/h
Ambient and personal dose equivalent rates 0.30 µSv/h – 420 mSv/h 0.43 µSv/h – 58 Sv/h
Intrinsic relative error for certification as a working standard of 1-st category (2-nd category) ±2.5% (±5%) for air kerma rate and exposure dose rate
±4.5% (±7%) for ambient and personal dose equivalent rates
Actual values of range limits and errors are determined by calibration
