Feature 1MEASURING RANGE: The measurement range of the nuclear radiation detector is 00.08uSv/h-9999uSv/h, which can be measured rays, Y rays, and X rays. 2GEIGER COUNTER: The nuclear radiation monitor uses Geiger counter tube, which is sensitive to sensing and ensures the accuracy of measuring results. 3CLEAR DISPLAY: Using a 0.96 inch TFT high definition screen to display instantaneous dose rate, cumulative dose, and average dose rate, with clear readings. 43 ALARM REMINDER: This handheld nuclear radiometer has sound, flashing light, and vibration over limit alarm reminders, timely alarms to ensure security. 5WIDE APPLICATION: This radiation dosimeter is suitable for household, hospital, nuclear power plant, laboratory, metallurgical industry and other scenes. 6ALUMINUM ALLOY: The radiation dosimeter shell is made of aluminum alloy, with anodized finish, corrosion resistance, and lanyard design for easy carrying.Item Type: Nuclear Radiation DetectorMaterial: Aluminum AlloyDetection Count: 48mm Geiger Counter TubeMeasuring Range: 00.08uSv/h-9999uSv/hWorking Environment: -10-50Product Voltage: 5VDCDisplay: 0.96 inch TFT HD LCD ScreenHumidity: 95%RH No CondensationDetection Ray Type: ray, x ray, rayPower Supply: 5V Lithium Battery (built in battery)Battery Capacity: 400mAhRange: 15-24 hoursApplication: Home, hospitals, nuclear power plants, laboratories, processing enterprises, metallurgy, etc.Key Description: 1. Shutdown Pause Button: Long press for 2 seconds to shutdown or power on, short press during startup to pause realtime data, short press again to continue real time data. Short press this button on any interface other than the main interface to return to the main interface function (pause or realtime icon reminder)2. Page Flipping Button: Short press to cycle through three functional interfaces, real time > maximum value+average value + total amount > bar chart (with interface navigation bar). Switching to the other two interfaces is a long term pause, unless switching back or short press 1 key to return to the main interface3. Mute Vibrate Button Rest Screen: Short Press to Cycle Between Reminder Modes: Only sound reminder, only vibration reminder, sound and vibration reminder, turn off reminder. This button only works in interface 1 and interface 2, and has no function in other interfaces (as other pages do not display sound and vibration reminder icons, other interfaces do not set the function of this button). Long press to rest the screen, Short press any button to light up during screen rest period4. Set Alarm Value: Short press to enter the alarm value setting. Short press once to set the maximum value alarm, and short press again to set the total amount alarm. Long press in these two interfaces to enter the settings, the alarm value will flash when setting, and short press the page turning button to select the alarm value. Short press again to save and exit. In the two interfaces of 4, if there is no operation for 5 seconds or if you press the 1 button briefly, you will save the current settings and exit the main interface.Software Interaction Logic: 1. Startup interface hello, shutdown interface good bye2. The alarm beeps and beeps for 1 second (triggered every time the alarm value is exceeded from low to high)3. Vibration reminder, with a reminder time of 0.5 seconds (triggered every time the alarm value is exceeded from low to high)4. The LED light of the host flashes, below the alarm value, it flashes green, once every 1 second, above the alarm value, it flashes red, once every 0.5 seconds5. When the real time data on the main interface is lower than the alarm value, a green value will be displayed, and when it exceeds the alarm value, a red value will be displayed .
