Features
- small and handy dose rate meter for the measurement of gamma radiation and X-rays
- measurand: ambient dose rate equivalent Ḣ*(10) and
ambient dose equivalent H*(10) (local dose) - built-in detector: energy compensated GM tube
- large, digital indication of measured values on LC-display (backlit)
- selectable simultaneous or separate indication of dose and dose rate, additionally analog indication of dose rate (logarithmic bar graph)
- display of the dose rate history as a search function for the detection of radioactive sources
- 4 preset dose and dose rate alarm thresholds
(on demand adjustment of customised alarm thresholds) - additionally switchable acoustic single-pulse indication
- automatic and continuous storage of the dose into a
non-volatile memory - storage of the dose and of set parameters even during battery change
- permanent self test
- designed for rough use, housing made of aluminium,
protection class IP54 (splashproof) - menu-driven user navigation
- supplied with robust nylon bag
- optional: external probes, probe cable
- connection facility for an external probe:
- 18526 D or ABG170 for contamination measurement (α, β, γ)
- immersion counter tube ZP1083 D (β, γ)
- NaI-scintillation probe 2002 for high-sensitive measurements (β, γ)
- with connected probe:
- display of measured values in cps
- display of the pulse rate history graph as a search function for the detection of radioactive sources or contaminations
- pre-selectable alarm thresholds: 2x background or 3x background
PLEASE NOTE: Detecting the personal dose requires a measuring
instrument with the measurand Hp(10).
