Personal Dosimeter A800726

The pocket radiometer is a new generation of multifunctional radiometer developed in accordance with the recommendations of the International Basic Committee on Radiation Health Protection and the provisions of the Chinese Basic Standards for Radiation Health Protection (
). It integrates dose rate and dose measurement, adds safety protection alarms and radioactive site divisions
Alarms, provides cumulative dose, is suitable for monitoring rays and rays, and is widely used in isotope radioactive worker protection detection, non-destructive testing, acceleration
br/> Personal safety protection monitoring for workers in the surrounding environment of nuclear medical equipment, nuclear medicine, irradiation, and laboratory nuclear facilitiesbr/> Instrument features
, Integrating dose rate and dose functions
, Adopt International and national radioactive health protection standards set alarms, dose rate measurement is automatic, continuous measurement, set radioactive sites and other alarm functions, adopt international unified units/(dose rate) and (cumulative dose) to directly display measurement Value
, four-digit LCD large screen display, clear displaybr/>, pocket-sized, easy to carry, low power consumption

When lit, it is the parameter setting state
The dose measurement value is a valid digit, and the measurement display unit is the cumulative display unit.
Power on and off
Press and hold the button for a few seconds to power on, and the buzzer will perform a self-check. First display the current software version number. Then the instrument automatically enters the dose rate measurement state.
Shutdown Press and hold the button for seconds, the display will turn off and the instrument will shut down.
Other operations (⊙), (▲)
Press the button to switch the display of cumulative dose and dose rate. Switch to the settings menu to set alarm thresholds, clear accumulated dose, mode settings, etc.
Measurement characteristics enable modification of a certain bit of the setting value in the setting menu. Press to change the value of this bit. After pressing the key to confirm the last input value, the modified or set value is saved.
