X - γ Radiation Dose Equivalent Rate Meter FD-3013B

The FD-3013B X - γ radiation dose equivalent rate meter is an enhanced version based on the original FD-71 series and FD-3013. It adopts an integrated structure, with more flexible measurement methods, wider measurement range, and higher measurement accuracy. Suitable for gamma radiation monitoring and inspection work in geological, mining, environmental protection, health and epidemic prevention, commercial inspection and other departments, as well as radiation medical, nuclear power plants, flaw detection, irradiation centers and other radiation venues.

main features

1. High sensitivity: using NaI (T1) crystal as the detector

2. Easy to operate: touch keyboard and Chinese prompts

3. Character dot matrix LCD display

4. Fast measurement setup time: displayed once per second

5. Reasonable, sensitive, and flexible alarm settings

6. The measurement display unit is the unified unit μ Sv/h and the commonly used unit μ R/h

7. Alarm function with battery undervoltage prompt

Main technical parameters

1. Detector: Ø 30mm × 25mm NaI (T1) crystal

2. Sensitivity: not less than 350cps/μ Sv/h (137Cs)

3. Energy threshold: 40keV

4. Measurement range: 0.01 μ Sv/h to 200 μ Sv/h

5. Relative inherent error ≤ ± 15%

6. Coefficient of variation ≤ 5.0%

7. Alarm threshold: The processor memory provides 0.25 μ Sv/h, 2.5 μ Sv/h, 10 μ Sv/h, and 20 μ Sv/h for users to choose from

8. Response time ≤ 5 seconds

9. Energy/incident angle response: The instrument indication value changes by less than ± 40% within the range of 60 keV to 3.0 MeV radiation energy and 0 º to 45 º incident angle

10. Power adaptability: Using two No.1 batteries, when the total voltage of the batteries drops to 2.2 ± 0.03V, an undervoltage alarm will be displayed, and the instrument can still work normally. Its response to radiation (calibration source) changes within ± 5%. The power consumption of the instrument during normal measurement should not exceed 200mW

11. Overload characteristics: When irradiated with uranium content equivalent that is 10 times larger than the display count rate value, the instrument should not be damaged and display a large display count of "200 μ Sv/h"; After the irradiation is completed, the instrument can automatically recover

12. Environmental conditions for use: The dose rate indicated by the instrument changes by ≤± 10% within the temperature range of 0 ℃ to+40 ℃; The dose rate variation indicated by the instrument within the humidity range of less than 93% (+40 ℃) should be ≤± 10% (excluding errors caused solely by temperature)

13. Dimensions: 430mm × 90mm × 220mm

14. Weight: 1.2kg (including the weight of two batteries)
