DA-175 α, β,γ Surface Contamination Meter

Product introduction

DA-175 α, β Surface Contamination Meter adopts dual detector design, which is used to monitor the α, β contamination level and γ radiation level of radioactive substances on the surface of personnel/items. It has the characteristics of accurate measurement, high sensitivity and convenient use, and can be used to inspect radioactive pollution in the environment. It can send out sound and light alarm according to the predetermined alarm threshold to warn the on-site staff and ensure the safety of personnel. It can be used for surface contamination detection of work surfaces, floors, walls, clothing, human skin, etc. in radioactive workplaces or laboratories.

Features

• The host has a built-in gamma detector, which can be used as a gamma dose alarm;

• Based on pulse shape discrimination, α and β particles can be distinguished and measured in real time;

• It adopts a 4-inch color touch LCD display and a full Chinese operation interface, which is easy to use and easy to operate.

• You can freely choose to deduct or not deduct the background, and the background measurement time is optional; the nuclide library can be edited freely.

• Data can be aggregated and stored for viewing by relevant personnel at any time.

• It has a real-time clock function, which can display the year, month and day in real time, and the operation of the clock will not be affected by power failure.
