Description
Overview
GAOTek geiger counter nuclear radiation detector mainly detects the personal cumulative dose equivalent HP (10) and personal dose equivalent rate HP (10) which occured by X, γ radiation, this dosimeter with LCD display. Dose and dose rate can switch by mode button, preset 3 grade dose rate and 1 grade cumulative dose alarm threshold, it will alarm with light and sound and LCD display when the value exceed threshold value. The data can be stored automatically during detection, the storage data can be read during standby mode and will not loss even if power failure, this dosimeter have the function that can prompt when dose increase, it is prompt by sound and light, built-in chargeable Li battery, easy to use, suitable for professional radioactive workers and general person using, provide the detection safety protection warning timely.
