Radiation ionization chamber monitoring instrumentICS-323C

This survey instrument has a wide measurement range. It can measure 1cm dose equivalent rate (1 μ Sv/h~300mSv/h) and 1cm cumulative dose equivalent (0.3~10 μ Sv). By opening the shielding cover in front of the ionization chamber, surface contamination of beta rays can be detected. Can be used for radiation detection in facilities for nuclear power, nuclear medicine, radioactive isotopes, accelerators, and X-ray machines.

Radiation ionization chamber monitoring instrumentICS-323CMain features:

1. Small in size and light in weight, easy to carry: weighing only 620g. Comes standard with shoulder straps, wristbands, and handles, suitable for use in various occasions.

2. Automatic zero adjustment: When the power is turned on, the zero adjustment is automatically performed, which is convenient to use.

3. Data storage: It can store up to 3000 measurement data (measurement date, dose rate value, cumulative dose value).

4. Waterproof design: daily waterproof drip structure

5. Compact design and rich functionality: capable of measuring 1cm cumulative dose equivalent (0.3 μ Sv~10 μ Sv); Use commercially available No. 5 batteries; Equipped with backlight illumination, it can be used in dark places; By using the Hold function, the current measured reading can be frozen. When it is difficult to observe the displayed value at certain measurement positions such as deep pipes, this function can be used to hold the measured value of the actual measurement location for easy reading. ）
