Real time dose rate, average dose rate, count rate, and record the cumulative agent at the same time; 2. The dose rate alarm threshold and dose alarm threshold can be continuously adjustable and set arbitrarily; 3. With timing dose function, the timing time is set arbitrarily between 0-999 hours; 4. The start date of the current cumulative dose can be viewed; 5. With dose rate and dose dual alarm function; 6. With sound, flashing light, vibration three kinds of alarm options; 7. When the radiation dose rate exceeds the measurement upper limit, it has the blocking alarm warning function (999MAX); 8. Built in memory, accumulated dose value, dose rate curve, dose curve data, alarm record, dose rate alarm threshold and dose alarm threshold data are not lost after power failure. Package List: 1 x Instructions  1 x USB Cable  1 x Host Features Radiation Dose Alarm: FS 5000 is a small medium to high range radiation dose alarm, the main function is to monitor X rays, gamma rays and beta rays. Achieve Accurate Measurement: The detector of this instrument is a glass Geiger counter tube (hereinafter referred to as Geiger tube), which is accurate and sensitive. TFT LCD Display: This product uses a 32 bit ultra low power microprocessor, and is equipped with 2.4 inch TFT LCD display, simple operation and has a strong anti interference ability. Sound Vibrtion Light Alarm: The equipment provides acousto optic shock alarm, and the alarm threshold is continuously adjustable. When the alarm threshold is reached, an alarm is issued to remind the staff to pay attention to safety.
