Probe program
The 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.
Product Highlights
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

-
Underwater measurements up to 30 m depth with optional pressurized water protection housing

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
