Automation und Messtechnik GmbH approved by PTB (government authority) Detector: Built-in GM counter 6150AD-15: useful range 1 mSv/h to 10 Sv/h 6150AD-18: useful range 2 µSv/h to 10 mSv/h Gets all the benefits from the 6150AD: Automatic range selection Smart time constant Digital calibration providing high accuracy Simultaneously measures current value, average value, and maximum value of dose rate, as well as dose Alarm thresholds for both dose and dose rate including one freely programmable threshold each May use probe cables up to 100 metres in length Power supply through probe cable, does not require a battery of its own, very low current consumption Robust waterproof aluminium housing Gamma Probes 6150AD-15 and 6150AD-18 External Probes for the Dose Rate Meter 6150AD® for Measuring Photon Radiation (Gamma and X-radiation) 6150AD® is our trademark (German registration number 303 55 582)

The Gamma Probes 6150AD-15 and 6150AD-18 are probes to be used with the Dose Rate Meter 6150AD to measure photon radiation (gamma and X-radiation). Both probes use a GM counting tube as the detector. They differ by the type of the built-in counting tube and therefore by dose rate range. If dose rates above 10 mSv/h are unlikely to occur, the 6150AD-18 is preferred, otherwise the 6150AD-15 with its high range up to 10 Sv/h. This data sheet only specifies the probes, not the 6150AD meter the probes are used with. It is assumed throughout this data sheet that the reader is familiar with the 6150AD...
