HRDmini-2 Electronic X & γ Rays Radiation Personal Dose Dosimeter
Function
The dosimeter is used to monitor the personal dose equivalent (DE) and dose equivalent rate (DER) for X & γ rays radiation. It can give out acoustic and optical alarm signals when the dose of DE or DER scales out the alarm threshold. The product adopts low power consumption single-chip microcomputer, which realizes the functions of real time display of the measured value, acoustic and optical alarm signals of the super threshold, EEPROM data storage, alarm threshold setting, detector fault alarm and battery undervoltage detection.
