Function of Individual Dosimeter |
Technical Measures of dosimeter |
Detector | GM counting tube |
Display | 4-digit LCD |
Measuring Range | Accumulated dose equivalent: Hp(10)0.0μSv-99.99mSv Dose equivalent rate :Hp(10)0.1μSv/h-99.99mSv/h |
Measuring Time | <6.0μSv/h 36s >6μSv/h ≤3.6s |
Dose Rate Response | <±20% (1μSv/h-99.99mSv/h) |
Energy Response | <±30% (50KeV-1.3MeV) |
Relative Error | <±20% (137Cs) |
Alarm Function | Within the measuring range, can initialize the alarm threshold value for the dose rate and the accumulated dose. This instrument has a fixed alarm threshold value. When the accumulated dose adds 0.1μSv every time, it will give a sound and a flash. When the accumulated dose≥50μSv the sound and flash will last for 5s, at the same time there will show the word of"ALARM". When the dose equivalent rate ≥25μSv/h,the sound and flash will last for about 6s,"ALARM"will appear. When the counting tube is blocked, the alarm will continue and not stop, and the "ALARM" will appear. The intensity of the alarm sound: about 80dB at 30cm away. |
Undervoltage Indication | When the voltage of the battery<2.7±0.05V,the under voltage symbol"LOBAT". |
Power Consumption | Two AAA 1.5V alkali batteries(7# battery).The power consumption<2mW,and can be continuously used for 720 hours. |
Temperature Characteristic | <±10% -10ºC+50ºC |
Humidity Characteristic | <±10% 0-95%RH(+35ºC) |
Exterior Size | 55(W)x 92(L)x 18(T) |
Weight | <75g (Including battery<98g) |
