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.
