GSM-115 survey meter, analog

The GSM-115 four range survey meter is a basic, rugged general purpose survey meter. The GSM-115 survey meter can be calibrated for G-M probes, sodium iodide detectors, plastic scintillation detectors, and alpha scintillation. The meter is analog, but consists of all digital microprocessor circuitry. This makes the meter small and lightweight. The tough aluminum and stainless steel housing provides maximum durability. Compatible with most probes, the GSM-115 Survey Meter will provide years of reliability for daily laboratory and field use.

There is one unit left, please consider upgrading to our digtial DSM-500 model.
