places around the X/gamma rays dose rate widely used in medical, nuclear industry High sensitivity to the environment

LH-III personal dose alarming device

Technical index

(1) the probe: GM count tube (the compensation)

(2) show: four LCD display, the cumulative dose dose rate, threshold, maximum dose rate and happen moments, clock, etc

(3) measurement range: cumulative dose equivalent: Hp (10) 0.0 u Sv-9999 mSv

Dose equivalent rate: Hp (10) 0.1 u Sv/h-99.99 mSv/h

(4) intrinsic error: < 10% (2 mSv/h or so)

(5) dose equivalent rate response: than plus or minus 20% (measuring range)

(6) energy response: than plus or minus 30% and keV electron volts)-1.3 MeV (trillion electron volts)

(7) the measuring time: 3 seconds

(8) memory: 64 K memory can store the data about a week, can bring the communication interface.

Based on user needs more LH-III supporting individuals radiation dose monitoring system software and computer system.

(9) alarm function: greater than the set the cumulative dose or absorbed dose rate is sound and light alarm threshold, and symbols show jam alarm, when count tube blocked, continuous alarm constantly, and symbols show alarm sound intensity in 30 cm place about 80 dB

(10) power consumption: AAA type 1.5 V alkaline batteries section (5 th battery) environment under the continuous use 900 hours

(11) temperature characteristic: 10 °C than-10%- + 50 °C

(12) humidity characteristics: than plus or minus 10% 0-95% RH (+ 35 °C)

(13) shape dimension: 55 (wide) x 75 (long) x 20 (thick) (mm), (21) weight: < 90 grams
