Thermo Scientific™ HP-210/HP-360 Series Pancake Geiger-Mueller Detectors
Alle ansehen Thermo Scientific ProdukteBeschreibung
Workplace safety in facilities that use radiation depends on frequent surveys to detect spills and prevent the spread of contamination in and beyond the lab. Thermo Scientific™ HP-210/HP-360 Series Pancake Geiger-Mueller Detectors are designed for daily contamination surveys on personnel, table tops, floors, equipment and any surfaces that could be exposed to radioactive material. Featuring a thin mica window protected by a stainless steel screen, HP-210/HP-360 meters permit sensitive detection of beta-emitting surface contamination that meets the environmental health and safety requirements of your lab.
HP-210/HP-360 Series Pancake Geiger-Mueller Detectors handheld probes provide sensitive alpha and beta detection featuring a “Pancake” Geiger-Mueller tube with a thin mica window.
General features of both probes:
- Open mica window protected by an etched stainless steel screen.
- High beta sensitivity; permits useful beta sensitivities down to 40keV and is alpha sensitive above 3MeV.
Features of the HP-210 Series Pancake Geiger-Mueller Detectors
- With optional sample holder "SH4A."
- The two versions offer both integrated shielding against radiation:
- HP-210T, with a high density tungsten shield, permits relatively low level beta monitoring in a gamma background; HP-210AL for low-level beta monitoring in a low background area; aluminum housing may be used.
Features of the HP-360 Geiger-Mueller Pancake Probe
- Capable of seeing low energy photons down to approximately 10keV.
- Economic product design with ergonomic enclosure constructed from rugged ABS plastic.
