Dosimeter MKS-85 "Schoolboy" is based on the classic high-sensitivity Geiger-Muller counter. The device features unique in its class weight and size characteristics (110x33x15 mm, 45 g), has a sensitivity of X-rays. The device has the ability to output dose graphics on it's own graphical indicator. Dosimeter-clock, MKS-85 "Schoolboy" is designed to control the level of radiation on the ground and on the premises, as well as to assess the radioactive contamination of materials, foodstuffs. The device is simple and reliable in operation and does not require special skills.

Dosimeter MKS-85GM is available in four versions: MKS-85 "Schoolboy" (base model), MKS-85B "Schoolboy" (with BLUETOOTH module and silicon-based counter), MKS-85F "Baby" (flash drive, without display), MKS-85GM (with Russian state metrological certificate). Please specify when ordering.

Technical parameters of the dosimeter MKS-85GM "Schoolboy" meet professional instrument, the instrument is certified Rostest and European CE certification.

Technical description and characteristicsDosimeter MKS-85GM "Schoolboy" for measuring seafood comes with plastic bags with a lock, as well as a liquid solution for decontamination of the body and contaminated sites "Deactivator-A".

Dosimeter MKS-85GM "Schoolboy" is designed for monitoring ambient dose equivalent rate of gamma radiation in the domestic environment (rooms, food, construction materials, soil, etc.) and can also be used by personnel working with sources of ionizing radiation. At the same time there is an accumulation of information on the dose received by users in the interest of his time, as well as display the current date, time and temperature.

The device has the following features:

- Changing the display information (display)

- The dose / dose rate / Clock / Schedule change dose

- Change the audio alarm thresholds

- Disable the alarm

- automatic account the temperature dependence of the measurement error

- Installation and display the current date and time

- Archive of measurements on 3276 records

- Installation of three different alarm threshold dose rate and dose

- Charging the internal battery via USB
