The FH 40 G is a
wide range survey meter, suitable for nearly all measurement tasks arising in radiation
protection: 
- Classic survey meter for personal radiation protection
- Stationary gamma dose rate meter
- System center with external probes for monitoring and
detection
View List of external detectors
- Simultaneous and discriminative gamma and neutron
measurement in mixed radiation fields, for x-ray/gamma dose rate and beta contamination,
for the highly sensitive proof of artificial gamma radiation even in variable natural
radiation fields ...
- System component in complex measurement systems
Features
- Measuring range from 100 nSv/h up to 100 mSv/h resp. 1 Sv/h
- One proportional counter tube for the entire range
- Sensitivity starts at 30 keV
- The instrument is approved by PTB for calibration and can be
calibrated in "air kerma" or in the new ICRU-units "ambient dose equivalent
H*(10)"
- Simultaneous operation of internal and external
detectors
- Many built-in functions -- very simple operation
- Configuration and data read out via PC
- Storage of up to 256 data records
- Waterproof (IP 67) and shock resistant
- ADF mode (Advanced
Digital Filter)
