Model GSM-115-HP Survey Meter with Pancake G-M probe

The Model GSM-115-HP system includes a four range survey meter and pancake G-M probe. This survey meter with G-M probe  is ideal for general purpose survey. It detects alpha, beta, and gamma radiation. The survey meter measures ¹⁴C, ³²P, ³⁵S & ¹³⁷Cs, with notable efficiency. The Model GSM-115-HP Survey Meter - external G-M probe is our most common and least expensive general purpose contamination monitor. Standard items provided with each system include the survey meter, probe, cable, batteries, operations and maintenance manual, and calibration certificate.
