Geiger counter - BR-9B (Kailishen BR-9B) - X-ray ruy β-ray, Dosimeter, Kyiv

A Kailishen device with radiometer and dosimeter functions in one portable case. Designed for convenient and comfortable use for measuring the flow density of X, B, Y particles, as well as X-ray radiation - both for one-time and long-term studies. The accuracy of the measurements allows the device to be used by both amateurs and specialists.
Dosimeter radiometer is used to detect and control the level of radiation or radiation background indoors and outdoors, in quarries, exclusion zone - it all depends on your needs. It can be used as a household dosimeter for measuring the radioactivity of food, building materials, and more.

Main functions and features
The radioactivity indicator (Geiger counter) is equipped with an informative LCD display for displaying results - it displays instantaneous and average measurements of the radiation background, as well as their graph.
There are no complicated settings and adjustments in the device, the necessary measurements can be made with one key press.
Measurement of radiation level and output of results on the device is carried out according to the international system of SI units - in Sievert (Zv);
The use of a halogen-gas (GM) tube as a sensor in the radioactivity meter allows for high sensitivity - from 80 mSv (0.8 MRN) - and a small measurement error (- 10%), in the result of which you can be absolutely sure. Due to the type of sensitive element used, the device is fragile and afraid of falling.
The radiometer (Geiger counter) is powered by three batteries (type AA, not included) and is designed for long-term autonomous operation. 

For particularly long-term measurements (for example, continuous measurement of the level of X-ray radiation in a hospital radiology room), the possibility of connection via a USB port is provided. There is no battery recharging function in this mode.
The radioactivity meter can be used to carry out radiological control of the area, products, household and industrial premises, in environmental tests and studies, in the organization of radiological protection, as well as radiation studies of pharmaceutical preparations.

A quick guide for beginners 

Insert three batteries (type AA) into the power compartment on the back of the device or connect it with a USB cable to a USB port;
Press ′ON′;(//tractor-service.com)
After turning on the device, press the central button to start measuring;
The radiation dosimeter (Geiger counter) will display the current indicators, as well as a graph of their change at the bottom of the display. After 8 minutes - the average radiation value corresponding to the received dose will be displayed;
If necessary, repeat measurements and reset the data - press the central key again;
After the measurements, press and hold the ′OFF′ key until it turns off (when connected from the USB port, the device is always on and does not turn off).
