x/gama-ray dosimeter
1,Product instruction: Type FJ2000 personal dosimeter is pocket-size instrument, it adopts the stronger functions, produced a new type of single chip microcomputer technology, X rays, and gamma rays are mainly used for monitoring, direct reading personal dose and dose rate; In measuring range, can be fixed or preset alarm threshold, more than the threshold value or blocked send out sound and light alarm, timely remind staff pay attention to safety. Equipment main technical indicators meet the national standards and international standards, is the current domestic similar instruments in the small volume, low power consumption pocket size machine wearing type, it is widely used in industrial nondestructive flaw detection, the nuclear power plant, isotope application areas such as cobalt and hospital treatment .
2,Characteristics: The sensitivity is high, background has also response to the environment Using single chip microcomputer technology, the function is complete, small volume
Low power consumption: < 2 mw equipment,operation is simple, easy to use
Cumulative dose, dose rate switch,electromagnetic interference resistance ability is high
3,Qualification:
(1) detector: GM counter (compensation)
(2)show:four LCD
(3) the measurement range (two functions) :
The cumulative dose equivalent: Hp (10) 0.0 mu Sv - 99.99 mSv
Dose equivalent rate: Hp (10) 0.1 mu Sv/h - 99.99 mSv/h
(4) measurement time: < 6.0 mu Sv/h 36 s > 6 mu Sv/h or less 3.6 s
(5) dose equivalent rate response: plus or minus 20% or less (1 mu Sv/h - 99.99 mSv/h)
(6) energy response: plus or minus 30% or less 50 kev - 1.3 MeV
(7)Relative error : <+ / - 20% (137 cs)
(8) alarm function:
Dose rate and cumulative dose within the measuring range can be preset alarm threshold. The instrument is presently is equipped with a fixed alarm threshold.
A,cumulative dose: every 0.1 mu Sv increased, a short sound, emitting one time; Acuity 50 mu Sv, sound and light alarm 5s, "ALARM" shows.
B, the dose rate: p 25 mu Sv/h, acousto-optic alarm about 6s, "ALARM" shows.
C, blocking alarm: when blocked tube count, continuous alarm, "ALARM" shows.
D, alarm sound intensity: about 80db at 30cm.
(9) undervoltage instruction: the battery voltage < 2.7 + / - 0.05 V, the instrument shows "LOBAT" battery undervoltage symbol.
(10) power consumption: AAA 1.5 V alkaline battery two batteries under this environment, the power consumption of < 2 mw, 720 hours of continuous use.
(11) temperature characteristic: ≤ 10% - 10 ℃ — + 50 ℃
(12) humidity: ≤ + / - 10% 95%RH (+ 35 ℃)
(13) shape size: 55 (width) x 92 (length) by 18 (thick)
(14) weight: 75g (including battery < 98 g)
4,Lead equivalent:0.35/0.5mmpb
