A full-range radiation survey device in the field environment.
MKS-U 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 device 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.
- Automatic setting of measurement intervals and ranges.
- Audio signaling of each registered gamma-quantum or beta-particle.
- Display and control keys backlight if operating in the dark. Storage battery (five AA nickel-cadmium batteries) charging by the built-in charger from:
– integral heliobattery;
– 12 V automobile battery;
– 220 V/50 Hz industrial network by voltage converter.
- Multilevel indication of power supply discharge.
- Ability to operate under atmospheric precipitation, dusty conditions and at immersion of the remote detector in water at 0.5 m depth.
- Measurement of gamma radiation DER action levels by placing the remote detector at up to 30 m distance.
- Analog indicator of radiation intensity.
- Up to 4096 measurement results recording in the nonvolatile memory with further transfer through infrared port to the computer.
- Viewing the recorded measurement results on the display.
- Ability to operate with the personal protective equipment (rubber gloves).
- Wide operating temperature range (-40…+50 °C).
- Display resistant to the temperature of up to +95 °C.
