High Performance JYSX1628 X/Y ray Radiation Dosimeter

 The portable radioactive contamination dosimeter is a wearable device,which id produced with the functionally powerful MCU technology.
 
 It is mainly for testing x-ray and y-ray, and directly reading the dose and dose rate.
 
 In the scope of its measurement, the alarming threshold can be fixed or pre-set.When the threshold is overrun or block dose happens, the meter will send out light and sound alarm signals. As a wearable device, it features small size and low power.
 It is widely used in such fields as non-destructive flaw detection, nuclear power station,nuclear submarine, isotope application, and cobalt therapy in hospital.
 
 Features:
 1. High sensitivity, and response to environmental background.
 2. Measuring both dose and dose rate, and providing various alarming signals.
 3. Low power, small size, and easy use.
 
 Technical parameter:
 1. Detector:GM counting tube, measuring X-ray and γ-ray;
 2. Display screen: 4 numbers LCD;
 3. Measuring range:
     Accumulated dose equivalent: Hp(10)0.0usv~99.99msv;
     Dose equivalent rate: Hp (10)0.1usv/h~99.99msv/h;
 4. Response time: 3.6S-36S;
 5. Measuring rate response: <±20%(1usv/h~99.99msv/h)
 6. Energy response: <±30%(50KeV~1.3MeV)
 7. Relative inherent error: <±20%(137Cs).
 8. Alarm function and alarm valve value: Measuring rate and accumulated dose can preset alarm valve value in the measuring range. The fixed alarm valve value as follows:
     1).Accumulated dose: Per increase 0.1usv, a short noise and light each time: ≥50 usv, sound-light alarm5s,"ALARM"display.
     2.) Measuring rate: ≥25usv/h,sound-light alarm is about 6s,"ALARM" display.
     3. )Clogging alarm: when counting tube clogged, alarm continuously, "ALARM" display, alarm sound intensity is about 80 decibels at the 30 cm.
 9. The battery under voltage indicates: when Battery voltage <2.7 +/- 0.05 Vs, the instrument displays under voltage symbol "LOBAT". It still can work for more than 24 hours in the lower radiation place after under voltage symbol appears.
 10. Battery and consumption: AAA type 1.5 V alkaline battery(7#battery), consumption<2mw, continuous service: 720 hours.
 11. Temperature characteristic: < ±10%- 10degree -- +50degree.
 12. Temperature features: <±10% 95%RH(+35%);
 13. Size: 55(width)×92(length)×18(thickness).
 14. Weight: <75g,including battery <98g.
