Geiger counter - Aikesi HFS-10 protective case, Radiation dosimeter. radiometer and dosimeter functions - in one portable case. Designed for convenient and comfortable use for measuring the flux density of X, β, γ particles, as well as X-ray radiation - both for one-time and long-term studies. The accuracy of measurements allows the device to be used by both amateurs and specialists.

Прилад компанії Aikesi з функціями радіометра і дозиметра - в одному портативному корпусі. Призначений для зручного і комфортного використання для вимірювання щільності потоку X, β, γ частинок, а також рентгенівського випромінювання - як для разових, так і тривалих досліджень. Точність вимірювань дозволяє застосовувати пристрій як любителям, так і фахівцям.
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 to measure the radioactivity of food, building materials, and more.

Main functions and features

Rubberized, protected case with a convenient clip.
The radioactivity indicator (Geiger counter) is equipped with an informative LCD display for outputting results - it displays instantaneous and average indicators of measurements of the radiation background.
It is possible to set the maximum value of the radiation background radiation level and a built-in sound alarm when it is exceeded, the noise level of which is regulated by the appropriate settings. Thanks to this, there is no need for constant visual control of the device itself - in any case, you will be informed about the radiation danger.
Measurement of radiation level and display of results on the device is carried out according to the international system of SI units - in Sievert (usv);
The use of a vacuum GM sensor as a sensor in the radioactivity meter allows you to ensure high sensitivity - from 80 mSv (0.8 MRN) - and a small measurement error (- 10%), the results of which you can be absolutely sure. Due to the used sensitive element of this type, the device is quite resistant to mechanical loads.
The Geiger counter is powered by a built-in lithium battery that can be charged via a USB Type-C port and is designed for long battery life. 

For particularly long-term measurements (for example, constant measurement of the level of X-ray radiation in a hospital radiology room), the possibility of connection via a USB Type-C port is provided. 
The radioactivity meter can be used to carry out radiological control of the area, products, domestic and industrial premises, in environmental tests and research, in the organization of radiological protection, as well as radiation research of pharmaceutical preparations.

A quick guide for beginners 

Press the power button for 5 seconds (middle upper button) - the device will turn on and beep or connect it with a USB cable to a USB port;
After turning on the device, wait a few minutes for the device to calibrate;
 To go to the settings menu, press any of the three buttons located on the front panel of the device;
With the far right button you can switch through the menu to the right side in a circle. Far left button - moves the menu selection to the left; Middle upper button - select the selected menu item;
The radiation dosimeter (Geiger counter) will display the current readings. After some time of use - the average radiation value corresponding to the received dose will be displayed;(//tractor-service.com)
If necessary, carry out repeated measurements and reset the data - through the Delete menu item;
After the measurements, press and hold the middle upper key until it turns off (when connected from the USB port, the device is constantly on and does not turn off).
