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 ***erage 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 variousprobesof 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 theScintillation Probe
• directly to be combined withTelescope Probe DEor"CE"-Telescopefor 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 H_x(photon dose equivalent rate)
• extensiveaccessories, e.g.probes, probe cable, leather bag "D", transport case (aluminium or plastic), accumulator, recharger, PC cable, etc.

Dose Rate Meter GRAETZ GammaTwin

• ***all, 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 functi*** and permanent self control (displayed by a function control symbol) guarantee operational safety and suitability for daily use
