Eberline PRM-6 count rate meter for scintillation detectors but can also use GM. Pulse count calibrated as well as volt meter calibration. Two versions were produced the PRM-7 which is a microR instrument with built in scintillator and audio divide scaled in units of microR . The PRM-6 has the same circuit board but without the add on board for audio divide as used on the PRM-7 scaled in units of CPM dial scale for external scintillator probes. High quality components military industrial grade capacitors and ruggedized meter all ICs have sockets. Low 10 mille Volt threshold to take advantage of the lower energy detection which the scintillator can see but would not register at higher thresholds Continuously adjustable response, reset button to zero meter, built in audio amplifier with external mounted speaker ( no additional battery required for audio ) Meter dial 0-500 C.P.M. with 4 decades of X1, X10, X100, X1K total to 500,000 C.P.M. also high Voltage scale with deck mounted Voltage control adjustable from 500 to over 1,600 Volts. The meter movement is a Gold vein suspension other wise known as taut band and is a sealed military grade meter. ( no jewels pivots, or hair springs ) Requires 2 D size batteries which are provided and installed. ( speaker and audio are powered by the main batteries no external battery needed ) SOME SWAG a new coil cord is also included which will fit both MHV & BNC fittings a $25.00 value, batteries, and probe holder for small scintillation probe. A complete service manual is provided in PDF format it covers both models PRM-6&7 includes the circuit for the audio divide that was used in the PRM-7 which is a Micro rem meter with a self contained scintillator the PRM-6 for external scintillators. P.S. the four holes in the side of the tub were for mounting a test source holder which didn't come with it. ( THE SCINTILLATOR PROBE, TEST SOURCE, and SIGN ARE NOT INCLUDED.)
