DatasheetThe GRAETZ probe program consists of calibratable gamma probes for the equivalent dose rate Ḣ*(10) and pulse probes for extending the measuring range of the dose rate meters from the GRAETZ-X5C series as well as the GammTwin S. Measuring probes are particularly suitable for use in poorly accessible measuring locations or for measurements from a safe distance. Here you get an overview of the different measuring probes from the GRAETZ probe program.
- Can be connected directly or via a probe cable up to 100 m long to the basic instrument; in calibratable use up to 30 m
- Automatic display of the types of radiation that can be detected with the probe on the basic unit
- Automatic probe detection by the basic unit
- For measurements in poorly accessible measuring locations
Calibratable gamma probes
for dose rate meters from the GRAETZ-X5C series
- Automatic adoption of the probe-specific calibration factor by the basic unit
- Calibratable gamma probes can be individually calibrated independently of the basic instrument
- Underwater measurements up to 30 m depth with optional pressurized water protection housing
- Temperature range: -30 °C to +60 °C
- Measured variable: H*(10)

Impulse probes
for dose rate meters from the GRAETZ X5C series and GammaTwin S
- Probes for α-, β- and γ-contaminations
- High sensitivity scintillation probe for β-/γ-detection
- Immersion probe for measurements in liquids
- Display range on basic unit 0 – 20 kImp/s
- Corresponding to the dose rate measurement with the gamma probes, a pulse rate measurement is carried out here with the basic unit, instead of dose measurement a summation of the pulses is carried out
- Instead of the four dose and dose rate warning thresholds, one pulse or pulse rate warning can be set for the basic unit in each case
