The FH 40 G is a versatile multipurpose Geiger counter and area monitor that can be used with external detectors for portable and remote area monitoring applications.
- Rugged, waterproof and reliable with very simple operation.
- Gamma meter with internal proportional counter tube.
- Integrated gamma dose rate measurements.
- Interface for one optional, external plug and play probe.
- Alarm thresholds for the internal detector and external probes of the FH 40 G are monitored simultaneously.
- Upon connection of an external plug and play probe, the probe parameters are automatically read into the FH 40 G and the correct parameters are set.
- High voltage generation inside the plug and play probe makes the system calibration independent of cable length.
- 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 (German version).
- Type tested for use by German fire brigades.
- Simultaneous operation of internal and external detectors, both dose rate and remote dose rate readings.
- Configuration and data read out via PC.
- Waterproof (IP 67) and shock resistant.
- ADF mode (Advanced Digital Filter).
- Clear, backlit LCD display.
- Datalogging capability.
- 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 optional barcode information.
- Wide range of plug and play external probes for monitoring and detection.
- 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.
Short summary of available plug and play probes:
- Gamma dose rate measurement: FHT 192 (ionization chamber), FHZ 632 (proportional counter), FHZ 612 (wide range), FHZ 302/312 (under water nuclear power).
- Gamma search probes: FHZ 502, 503, 512 (NaJ/BGO).
- Contamination: FHZ 742 (Scintillator), FHZ 732 (Pancake/proportional counter), FHZ 382 (Scintiallator + Alpha/Beta discriminator via LED indication if alphas are present).
- Aritificial radiaiton discrimination: NBR probe FHZ 672.
- Preamplifiers for various classic probes.
- Wide range of accessories like cables, telepoles, application specific kits, etc.
