Dose Rate Measuring System GRAETZ X 5 Cplus
|
- PTB-approved dose rate meter for measuring gamma radiation and X-rays
- measuring size: ambient dose equivalent rate H*(10)
- detector: energy compensated Geiger-Müller-tube
- large digital indication of measured values on LC display (illuminable)
- selectable dose rate or dose indication with integration time
- additional quasi-analog dose rate indication (3,5 decades, logarithmic bar graph)
- indication of peak and average dose rate value
- 4 free programmable dose and dose rate alarm thresholds
- automatic or manual storage of dose and dose rate values together with date and time
- evaluation/indication of residual time for staying in the current radiation field with regard to the maximum allowed dose
- switchable acoustic single-pulse indication
- clear menu-driven operator guidance for easy operation, partly secured by password
- storage of set parameters also when device is switched off or during battery replacement
- continuous self testing and monitoring ensures high reliability
- compact, metallized housing made of high impact-proof plastic (easy to decontaminate), sealed for submersion up to 1 m depth (IP 67)
- power supply by 9V battery 6LR61 or alternatively by 9V accumulator (option)
- EMC-screened
- RS-232 interface
- basic unit can be combined either directly or by probe cable with various probes of the GRAETZ probe programme for
- extending the measuring range up to 10 Sv/h
- detecting alpha, beta and gamma radiation
- measuring in liquids
- measurements at "hard-to-get-to" places
- for measuring low dose rates by means of the Scintillation Probe
- directly to be combined with Telescope Probe DE or "CE"-Telescope for measurements from a safe distance
- automatic probe identification
- when using GRAETZ "CE"-probes: measuring size H*(10) (ambient dose equivalent rate)
- when using GRAETZ "D/DE"-probes: measuring size Hx (photon dose equivalent rate)
- extensive accessories, e.g. probes, probe cable, leather bag "D", transport case (aluminium or plastic), accumulator, recharger, PC cable, etc.

Dose Rate Meter
GRAETZ GammaTwin
|
- small, handy and easy to operate dose rate meter for the measurement of gamma radiation and X-rays
- measurand: ambient dose equivalent rate H*(10)
- detector: energy compensated Geiger-Müller-tube
- large, digital indication of measured values on LC-display (illuminable)
- selectable simultaneous or separate indication of dose and dose rate, additionally quasi-analog indication of dose rate (logarithmic bargraph)
- 4 preset dose rate alarm thresholds
- 4 preset dose alarm thresholds
- acoustic single-pulse indication can be switched on; especially for the use in non destructive testing it is possible to reduce the pulse rate of background radiation to 1-2 counts/minute (to be set in a special menu point)
- automatic and continuous storage of the dose
- storage of the dose and of set parameters even during battery change
- continuous test functions and permanent self control (displayed by a function control symbol) guarantee operational safety and suitability for daily use
- designed for "heavy-duty" use, housing made of aluminium, protection class IP54 (splash proof)
- menu-driven user navigation
- power supply by 2 standard batteries type AAA 1,5V
- supply together with a robust Nylon bag and an earphone for loud work environments
