johnson radiation survey meter with geiger (gm) probe
This popular configuration includes the GSM-115 meter paired with the HP-265 probe. The GSM-115 is a microprocessor-controlled instrument for the budget minded. It is a digital instrument with an analog display. Comes standard with probe-saturation and other error indicators. The HP-265 is the best all purpose detector available. It is a pancake G-M detector sensitive to most alpha, beta, & gamma Radiation.
