Feature: 1. APPLICABLE SCENARIO: Nuclear radiation detector is suitable for a variety of scenes, like home, hospital, nuclear power plant, laboratory, processing enterprises, metallurgy and so on 2. RADIATION DETECTION: Geiger counter technology tube, counting instrument for detection of nuclear radiation(β ray, Y ray and X ray) strength, possess high sensitivity 3. ALL ALUMINUM ALLOY SHELL: The dosimeter meter adopts aluminum alloy shell, after anodizing process, possess special texture; Designed with lanyard, compact and portable 4. ONE KEY START: The X Y β ray tester is started with for Geiger‑Mueller counter tube, with sensitive induction, to ensure the accuracy of measurement results 5. CLEAR DISPLAY: Geiger meter with TFT HD display, showing instantaneous dose rate, cumulative dose rate, average dose rate, easy to observe in different light environment, easy to read 6. THREE KINDS OF ALARM REMINDER: Geiger meter has sound, flashing light, vibration over limit alarm warning, timely alarm to ensure safety Specification: Item Type: Nuclear Radiation Detector Material: Aluminum Alloy Detection And Counting: Approx. 48mm / 1.89in Geiger counter tube Measuring Range: 00.08uSv/h~9999uSv/h Working Environment: -10-50℃ Display: 0.96in TFT high definition LCD display screen Humidity <95%RH no condensation Detection Ray Type: γ ray, X ray, β ray Power Supply: Lithium battery 5V Battery Capacity: 400mah Endurance: 15~24 Hours Application: Home, hospital, nuclear power plant, laboratory, processing enterprises, metallurgy and so on Key Description: 1. Power off, Pause button, Return to the main interface, Long press for 2 seconds to power off or power on. During startup, short press to pause real time data and press again to continue real time data. Short press this button in any interface except the main interface to return to the main interface function (pause or real time icon reminder). 2. Page flipping button, press to cycle between the three functional interfaces: Real time > Maximum + average + total > bar chart(with interface navigation bar). When you switch to the other two interfaces, you will stay for a long time unless you switch back or press 1 button to return to the main interface. 3. Press the Mute, Vibration Button, or Video Screen to switch the reminder mode: Sound reminder only, Vibration reminder only, Sound and vibration reminder, Close reminder. This button only works in interface 1 and interface 2, this button has no function in other interfaces(because other pages do not display sound and vibration reminder ICONS, so other interfaces do not set the function of this button). Long press is breathing screen, short press any button during the screen to light up. 4. Set The Alarm Value By Short Press To Enter The Alarm Value Setting: Short press once is the maximum alarm, short press again is the total alarm. Long press in these two interfaces to enter the setting. When setting, the alarm value will flash. Short press the page turning button to select the alarm value. Press again to save and exit. If no operation is performed in the two interfaces of 4 for 5 seconds or press 1 button, save the current settings and exit to the main interface. Interaction Description: Software Interaction Logic: 1. The startup screen is hello, and the shutdown screen is good bye. 2. Ring alarm tone beep, the warning time is 1 second (every from low to high, the alarm value is triggered once). 3. Vibration reminder, reminding time is 0.5 seconds (every from low to high, more than the alarm value triggered once). 4. The LED light of the host blinks green if it is lower than the alarm value, once in 1 second; if it is higher than the alarm value, it blinks red once in 0.5 second. 5. When the real time data of the main interface is lower than the alarm value, the green value will be displayed; when the real time data exceeds the alarm value, the red value will be displayed..
