SDM2000U Personal Dosimeter Function The dosimeter is used to monitor the personal dose equivalent ａnd dose equivalent rate of X, γ radiation. DE, DER ａnd total working time can be read out switched by pressing function button. It incorporates audile, visual ａnd LCD indicator alarms to warn user when preset dose/dose rate threshold levels are exceeded. The threshold can be set random in measurement range. Real-time measurement data can be storage in non-volatile memory that will not lose after power off. Record data can be transmitted through infrared communication to the Record Reader, ａnd the reader can communicates with computer via RS485 mode interface transport. Dosimeter can be used alone or with the reader ａnd computer network data management system. Features 1、Wide-range, low power consumption, resistance to overload 2、Real-time an Non-volatile data record 3、Displaying cumulative dose, dose rate ａnd working hours 4、Audio, visual ａnd LCD indicating over-threshold alarm 5、Threshold can be set in measurement range 6、Standardized measurement data can be managed by professional software via IR communicator 7、Advanced design to ensure the safety ａnd reliability of measurement Specifications 1、measurement range：Hp（10）: 0.01Sv10Sv Hp（10）: 0.1Sv/h1Sv/h 2、Alarm threshold Continuously set .during measurement range for dose ａnd dose rate. Dose increment alarm: can be set during 1Sv999Sv Over time: 16000min 3、Alarm Gives audile, visual ａnd LCD indicating alarm for over-threshold, under-voltage, over time, detector failure ａnd DE increment tips. Sound intensity > 80dB （@30cm） 4、LCD Display Hp（10）: 0.00Sv9999mSv Dose rate Hp（10）: 0.01Sv/h1999mSv/h 5、energy response <±30%（50keV1.5MeV） 6、DR response <±20% （1Sv/h10Sv/h） <±15% （10Sv/h1Sv/h） 7、Overload：>20Sv/h 8、Power：One AA size Lithium Battery 3.6V 9、Battery Life >2000h. 10、8 hours last when under-voltage alarms 11、Temperature <±10%, -10℃+40℃ 12、Humidity <±10%, 40%90%RH（35℃） 13、Weight 95g 14、Dimensions 90×62×25（excluding clip） |
