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.
