Cs with angle ± 75°
„
Measurement and display
:
‰
X-ray and gamma energy range: 15 keV to 7 MeV

Display units : mSv, µSv, or mrem
„
Display dose
: 1 µSv to 10 Sv (0.1 mrem to 1000 rem)
„
Display rate
:
0.01 mSv/h to 10 Sv/h (1 mrem/h to 1000 rem/h)
or 0.001 mSv/h to 10 Sv/h (0.1 mrem/h to 1000 rem/h)
(extended option(**))
„
Measurement range :
‰
1 µSv to 10 Sv (0.1 mrem to 1000 rem)
‰
0.1 µSv/h to 20 Sv/h (0.01 mrem/h to 2000 rem/h)
‰
Saturation indication : above 10 Sv (1000 rem)
or 10 Sv/h (1000 rem/h)
„
Dose rate linearity :
≤ ± 20 % up to 10 Sv/h (1000 rem/h) (Co and X H30 20 keV)
(**) - Mandatory if rate alarms are set below 50 µSv/h
(5 mrem/h) in order to display rate with better accuracy, if
fast response time for rate alarm is not required.
- Recommended for rate alarms settings below
100 µSv/h (10 mrem/h), if fast response time for rate alarm
is not required.
