Radiation Monitoring Device Mini Personal dosimeter HRD-II in the weight 36g large with Dose rate Range 1mSv/h~1Sv/h
Small type,wide measure range, display and storage dose rate and cumulative dose measurement.
Preset 3 grade dose rate and 1 grade cumulative dose alarm threshold, will remind if dose increase.
Built-in Chargeable Li battery, easy to use.
Function:
This personal dosimeter mainly detect the personal cumulative dose equivalent HP(10) and personal dose equivalent rate Hp(10) which occured by X,γ radiation, this dosimeter with LCD display. Dose and dose rate can switch by mode button, Preset 3 grade dose rate and 1 grade cumulative dose alarm threshold, it will alarm with light and sound and LCD display when the value exceed threshold value. The data can be stored automatically during detection, the storage data can be read during standby mode and will not loss even if power failure, this dosimeter have the function that can prompt when dose increase, it is prompt by sound and light, built-in chargeable Li battery, easy to use, suitable for professional radioactive workers and general person using, provide the detection safety protection warning timely.
Main parameter:
| Detector | Semiconductor detector | |
| Detect range | Dose rate:1mSv/h~1Sv/h；Cumulative dose : 0.01mSv~10Sv | |
| Alarm threshold | Dose rate threshold:①0.5mSv/h,②2.5mSv/h,③10m Sv /h；Cumulative dose threshold:① 1mSv； Dose increase prompt value:1mSv. Above value also can be set according to customer. | |
| Alarm settings | Dose rate threshold ,Cumulative dose threshold,Dose increase prompt,low power ,and detector failure alarm. | |
| Alarm way | Alarm with beeper,LED , LCD display. Alarm with different grade beeper and LED for different grade dose rate threshold value, also display the corresponding dose rate value. Alarm sound intensity above 75dB when the distance is 30cm between the place to dosimeter. | |
| Data storage | Storage the cumulative dose value and the maximum dose rate value, include the relative time when it occur maximum dose rate value, data will not loss if power failure, can be read when standby mode. Data will be zero if restart the dosimeter, The values which can be read during standby mode are: Cumulative dose value, Cumulative dose time, maximum dose rate value, relative time when it occur maximum dose rate value, machine number, etc. | |
| Energy response | <±30%(50keV~1.5MeV) | |
| Dose response linear | <±20% (0.1mSv/h~1Sv/h)
| |
| Relative intrinsic error | <±10%(1.5mSv/h) | |
| Overload characteristics | Above 10Sv/h | |
| Power | Built-in 3.6V chargeable battery,first working time >400hours；charging time:< 4 h | |
| Temperature | <±15%, -10℃~+40℃ | |
| Humidity | <±10%, 40%~90%RH(35℃) | |
| Size/ weight | 70mm×38mm×16mm / about 36g | |
| Optional accessory | Charging adapter(AC220V/50Hz or AC110V/60Hz). | |
