Home Radiation Monitor

The НRM is used for domestic purposes: to monitor the radiation purity of the surrounding area, provided that its detecting unit is located on the facade of the house, as well as residential premises, buildings and structures, if its detecting unit is located inside the building.

To obtain information about our products during the preparation of tender or contractual documentation, please contact our representatives via the provided contacts. We continuously improve our products and expand their functionality in line with market needs by applying the latest technologies, modern components, and materials. Therefore, specifications, descriptions, and configurations are subject to change without prior notice.

Features

Due to the built-in WiFi module and a special built-in web interface, HRM can also be used to form a radiation monitoring network
The НRM provides for setting two threshold levels of sound and light alarm in the range from 0.01 μSv/h to 9.99 mSv/h with a resolution of 0.01 μSv/h. If the threshold levels are exceeded, it is accompanied by an alarm with different sounds for each threshold and a change in the color of the display backlight from white to red
The built-in temperature sensor in the BDBG-20 detecting unit makes it possible to measure the ambient temperature at its location

Purpose of Use

The НRM is designed for continuous monitoring of the radiation gamma background in the environment by measuring the ambient dose equivalent rate (DER) of gamma radiation, as well as for sound and light signaling in case of an increase in the level of radiation above the established threshold levels
