Nuclear Radiation Detector: This instrument is mainly used for radiation monitoring of X, γ and β rays.With detection sensitivity.It is widely used in nuclear power plant, accelerator, iron & steel industry, chemical industry, isotope application, industrial X and y non-destructive flaw detection, Y radiation.
5 Measurement Units Switchable: Dosage rate in the unit of u Sv/h, u Gy/h and m R/h, CPS, CPM.
Alarm Function: The instrument can preset the alarm value of dosage rate and accumulative dosage.Three selective alarm modes design: sound, light and vibration.
-time Measurement: -time measurement and display of dosage equivalent rate and accumulative dosage in the work area.
Permanent Data Storage Upon Power Cutoff: The calendar, time and accumulative data can be stored permanently during the battery replacement. With low power consumption and battery under-voltage indication function.
