Gamma dosimeter with GPS MKS-UM measures gamma radiation dose rate from the background to emergency levels.

Availability of the remote detector enables measuring emergency levels of gamma radiation dose rate at a distance of 30 m. The dosimeter operates under the conditions of atmospheric precipitations, dusty conditions and when the remote detector is submerged in the water at 0.5 m depth.

Storage battery of the device is charged with the help of the built-in charger from integral solar battery, from automobile battery or from industrial network.

The device has the nonvolatile memory, and the recorded results can be viewed on the display and transferred to the PC.
Gamma dosimeter with GPS can be assembled as requested by the customer.
Features
- Possibility to measure ambient dose equivalent rate (DER) of gamma radiation with the detector which is built in the control panel.
- Automatic selection between measurement intervals and ranges.
- Audio signalling of each registered gamma-quantum or beta particle.
- Backlit indicator and control keys for operation in the dark.
- Rechargeable lithium-ion battery charging by the built-in charger from:– internal solar battery;– 12 V automobile battery;– 220 V/50 Hz mains power using a voltage converter.
- Multilevel indication of battery discharge.
- Operates under conditions involving atmospheric precipitation, dusty atmosphere (IP67).
- Analog indicator of radiation intensity.
- Logging of up to 1500 measurement results tagged to location coordinates in the nonvolatile memory via infrared port to the PC (built-in GPS/GLONASS receiver).
- Viewing of logged measurement results on the display.
- Easy to operate even if wearing personal protection – rubber gloves.
- Wide operating temperature range – from -30…+55°C.
- Display temperature resistance – +95°C.
Detector types
- Gas-discharge Geiger-Muller counters without return run of counting response
