1. According to the measurement object, 1000 different address numbers from "000" to "999" can be set at once, and various measured data can be automatically recorded and stored in the instrument. According to user needs, it can be queried separately or input into the upper computer through infrared communication for statistical processing;
2. In addition to the general dose rate and cumulative dose exceeding threshold alarm function of the dosimeter, this instrument is also designed with a dose frequency alarm function, and there are five modes of alarm frequency to choose from: 0.001 μ Sv, 0.01 μ Sv, 0.1 μ Sv, 1 μ Sv, and 10 μ Sv. It can use sound and red lights to indicate the frequency of dose increase values when it is inconvenient to read;
3. The instrument display screen has a large area, which can not only display dose rate values but also intuitively display analog indicator values. It can automatically shift gears and display according to the dose rate in three stages. They are: 10 nSv/h to 1 μ Sv/h, 1 μ Sv/h to 100 μ Sv/h, and 100 μ Sv/h to 10 mSv/h;
4. In order to provide users with a more accurate understanding of the reliability of the measured values, the instrument displays the current dose rate value while also indicating the uncertainty of the displayed value;
5. The instrument display screen is equipped with a backlight function, which can clearly see all characters on the screen even at night when the backlight is turned on. The backlight can be easily turned off, and if you forget to turn it off, the instrument will automatically turn off after 15 seconds to save labor;

6. The instrument is equipped with a power switch. When the power is turned off, the instrument stops measuring and alarms, but the timing will not stop. The data recorded and stored by the instrument will not be lost. At the same time, the instrument also has a "off display" (false shutdown) function. When there is no need to view the display, the instrument can save more labor in the "off display" state, while other functions are not affected;

7. The instrument has a small volume, sturdy structure, low power consumption, and is equipped with two ordinary alkaline No. 5 batteries. It can be used continuously for no less than 800 hours near the background radiation field.
