3007K personal dose alarm device (wrist type)

Personal dose alarm (wrist type) This instrument is a new generation multifunctional radiometer developed based on the recommendations of the International Committee on Radiological Health Protection (ICRP) (1997) and the Chinese Basic Standards for Radiological Health Protection (GB-4792-84). Integrating dose rate and dose measurement, adding safety protection alarms and classification alarms for radioactive sites, providing cumulative dose, suitable for monitoring X-rays and gamma rays, widely used in isotope radioactive worker protection testing, non-destructive testing, accelerators, nuclear medicine, gamma irradiation, and personal safety protection monitoring of workers in the surrounding environment of laboratory nuclear facilities.

Personal dose alarm device (wrist type) features:

1. Integrating dose rate and dose function

2. Adopting international and national radiation health protection standards to set alarm thresholds

3. Dose rate measurement is automatic, continuous, and equipped with alarm functions such as setting up "radioactive sites"

4. Using internationally unified units: μ Sv/h (dose rate) and μ Sv (cumulative dose) to directly display measurement values

5. Four digit LCD large screen display, clear display

6. Pocket sized, easy to carry, low power consumption

Brief Operating Instructions for Personal Dose Alarm Device (Wrist)

The operating interface of the personal dose alarm (wrist type) consists of a display screen, an alarm buzzer, and two buttons: OK (⊙) and FUN (▲).

The LCD screen provides visual information feedback, including battery information, alarm conditions, and radiation dose detection values.

LCDLCD Display (Introduction to Display Symbols)

Dose accumulation: 15 with high precision

Rate Dose rate: 30 Low precision

Setup setting: Battery

The personal dose alarm (wrist type) measures a dose with 4 significant digits, displaying the measurement unit in μ Sv/h and the cumulative display unit in μ Sv.

Personal dose alarm device (wrist type) power on and off

Power on: Press and hold the "OK" button for 3 seconds to turn on the device, and the buzzer will perform a self-test. Display the current software version P1.00 first. Subsequently, the instrument automatically enters the dose rate measurement state.

Shutdown: Press and hold the "OK" button for 5 seconds to turn off the monitor and the instrument.

Other operations: OK (⊙), FUN (▲)

1. Press the "OK" button to switch between displaying cumulative dose and dose rate.
2. Switch to the settings menu with 'FUN', set alarm thresholds, reset cumulative dose, mode settings, etc.

Press the "OK" key in the settings menu to modify a certain setting value, and press "FUN" to change the value of this position. After pressing the "OK" button to confirm the last input value, the modified or set value is saved.
