  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. More 

  The device has the nonvolatile memory, which can store up to 4096 measurement results. The recorded results can be viewed on the display and transferred to the PC.

  The device can be assembled as requested by the customer.

  Ukrainian peacekeepers of the 19th NBC battalion have successfully used MKS-U in the Middle East. In severe desert conditions the MKS-U gained an excellent reputation of a reliable, precise and trouble-free device.

  MKS-U is in operational service with the Ukrainian Army, it is included in the equipment list of the Ukrainian MES units, supplied for the purposes of the Security Service of Ukraine, Ministry of Internal Affairs of Ukraine, the Border Guard Service of Ukraine, etc.

  Since 2002 according to the international technical assistance programs MKS-U devices have been supplied to the Border Guard Service of Ukraine, Internal Troops of the Ministry of Internal Affairs of Ukraine, the Ministry of Emergencies of Ukraine, the Border Services of Kazakhstan and Uzbekistan.
