Product Description

Wireless Watch Type Sound And Light Alarm Personal Dosimeter Dose Rateradiation Measurement


General introduction

Wrist-type personal dosimeter is mainly used to monitor X γ, it particularly suitable for the medical application of interventional radiotherapy. The dosimeter is controlled by a low-power single-chip microcomputer, which realizes LCD drive display, measurement data storage, relevant parameter setting, detector fault alarm, battery voltage detection, over-threshold acoustooptic alarm, wireless communication, wireless charging and other functions.


Main technical indicators

Detector Silicon semiconductor detector
Measuring range Hp(10): 0.0Sv10Sv
H’p(10): 1Sv/h1Sv/h
Alarm threshold

Hp(10): 1continuously adjustable between Sv10Sv

H’p(10): 1continuously adjustable between Sv/h1Sv/h


Alarm sound-light and LCD indication alarm, and the cumulative dose and dose rate exceed the threshold, Battery undervoltage, working overtime and detector failure alarm

Audio-visual indication of different cumulative dose increments

LCD display
