The FH 40 G is a wide range digital survey meter, suitable for nearly all measurement tasks arising in radiation protection.
- Rugged, waterproof and reliable with very simple operation
- Versatile multipurpose meter and area monitor
- For use with external detectors for portable and remote area monitoring applications (cable of up to 50m can be used)
- Gamma meter with internal proportional counter tube
- Internal detector and external probes of the FH 40 G are monitored simultaneously
- No requirement for external probe or cable for gamma dose rate measurements
- Upon connection of an external probe, the probe parameters are automatically read into the FH 40 G and the correct parameters are set
- Separate alarms can be set by the user for both the internal and external detectors
- Operational internal proportional detector and connected external detector
- Serial infrared interface
- Type tested by PTB (Germany) in Hx or H*(10)
- Type tested for use by fire brigades
- Calibrated in “air kerma” or in the new ICRU-units “ambient dose equivalent”
- Simultaneous operation of internal and external detectors, both both dose rate and remote dose rate readings
- 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)
- Clear, backlit LCD display
- Data logging
- Internal diagnostics ensure proper functioning of the detector(s) and the electronics
- Designed to record up to 256 data points containing measurement number, date, time and dose rate at the internal detector and external detector, status, and barcode information
All FH 40 G versions and external probes containing the “-10” suffix are designed to meet the energy response behavior of the new SI-units ambient dose equivalent and ambient dose equivalent rate according to ICRU 39.
Ordering Alerts: Available with a large number of external detectors; FH 40 G versions are also available with an additional earphone output.
