Description

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.

Features

  • 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.
