Radioactivity detector

Radiation/radioactive detector/radiation detector/personal dosimeter/ray detector (domestic advantage)

Features:
The fj3500 personal dosimeter is a smart pocket instrument. It is manufactured using the latest, more powerful microcontroller technology. Mainly used to monitor X-rays and gamma rays. Within the scope of measurement, various threshold alarm values ​​can be arbitrarily set, and sound and light alarms are generated to promptly alert the staff to safety. The instrument has a large memory and can store about one week of data. The main technology of the instrument complies with national standards and international standards. It is a portable pocket instrument with strong functions, small size and low power consumption in similar domestic instruments. It is widely used in nuclear military industry, nuclear submarines, nuclear power plants, industrial non-destructive testing, isotope applications and hospital cobalt treatment, protection of occupational diseases, and monitoring of background radiation levels of residents around nuclear power plants.

main feature:
● Large amount of data storage, with 1500 hours of data storage capacity.
●Threshold alarm is continuously adjustable, with cumulative thresholds for dose, dose rate, blocking, overtime, etc. ● Automatic recording of various data, power failure, or replacement of battery data without loss ● Displayable, cumulative dose, dose rate, working time, maximum Dose Rate Occurrence Time and Size, Accumulated Dose Threshold, Dose Rate Threshold, etc. ● Sensitivity is high, and it responds to the environment background. ● Small size, easy operation, and strong resistance to electromagnetic interference. Technical Index:
(1) Detector: GM counter (compensated)
(2) Display: 4-digit LCD can display cumulative dose, dose rate, threshold, maximum dose rate and time of occurrence, clock, etc. (3) Measurement range: Cumulative dose equivalent: Hp(10) 0.0μSv-9999mSv Dose equivalent rate: Hp (10) 0.1μSv/h-500mSv/h
(4) inherent error: <10% (about 2 mSv/h)
(5) Dose equivalent rate response: ≤ ± 20% (within the measurement range)
(6) Energy response: ≤±30%50 KeV-60Co
(7) Measurement time: 300 seconds - 1 second automatic switching (8) Memory: 64K Memory can store about a week of data (9) Alarm function: When there is more than the set cumulative dose or dose rate threshold, there is sound and light alarm, and The symbol indicates the blockage alarm. When the count pipe is blocked, the continuous alarm will not stop and the symbol indicates that the alarm sound intensity is about 80dB at 30cm.
