Feature: 1. GM COUNTING TUBE: GM counting tube is adopted to ensure high sensitivity and the accuracy of measurement results. 2. TFT HD SCREEN: With TFT high definition display screen, easy to observe in different light environments and easy to read. 3. MULTI FUNCTION: The detector can detect β γ X ray, display instantaneous dose rate, cumulative dose, average dose rate. 4. SAFETY ALARM: The Geiger counter has three kinds of alarm reminders, sound, flashing light and vibration, timely alarm to ensure safety. 5. WIDE APPLICATION: The meter can be used for home, hospital, nuclear power plant, laboratory, processing enterprise, metallurgy, etc. Specification: Item Type: Nuclear Radiation Detector Material: Aluminum Alloy Model: PW07 Detection Count: 48mm Geiger counter tube Measuring Range: 0.08uSv/h to 10mSv/h Working Environment: -10℃ to 50℃ Voltage: 5V DC Display: 0.96 inch TFT HD LCD Humidity: ≤95% RH without condensation Detection Ray Type: γ ray, X ray, β ray Power Supply: Lithium battery 5V (built in) Battery Capacity: 400mah Duration: 15-24 hours Application: Home, hospital, nuclear power plant, laboratory, processing enterprise, metallurgy, etc. Key Description: 1. Shut Down, Pause Button, Return To Main Interface: Press and hold for 2 seconds to turn off or on. During power on, short press to pause real time data, and short press again to continue real time data. Short press this key on any interface other than the main interface to return to the main interface function (still with pause real time icon reminder). 2. Page Turning Button: Short press to cycle to switch three function interfaces: real time, maximum average and total, histogram (with interface navigation bar). Switch to the other two interfaces could stay for a long time, unless you switch back or briefly press 1 key to return to the main interface. 3. Mute, Vibrate Button, Rest Screen: Short press to cycle to switch reminder mode: only sound reminder, only vibration reminder, sound and vibration reminder, close reminder. This button only works in interface 1 and 2. In other interfaces, this button has no function (because other pages do not display sound and vibration reminder icons). Long press is the rest screen, short press any button to light up during the rest screen. 4. Set Alarm Value: Short press to enter the alarm value setting, short press once is the maximum alarm, and short press again is the total alarm. In these two interfaces, press and hold to enter the setting, and the alarm value will flash when setting. Short press the page turning key to select the alarm value. Short press again to save and exit. There is no operation in the two interfaces of 4 for 5 seconds or press the 1 key briefly to save the current setting and exit to the main interface. Interactive Description: Software Interaction Logic: 1. Power on interface: hello, power off interface: good bye. 2. The alarm prompt beeps and beeps for 1 second (it is triggered once when the alarm value is exceeded from low to high). 3. Vibration reminder, the reminder time is 0.5 seconds (every time the alarm value is exceeded from low to high, it is triggered). 4. The LED light of the host flashes, the green light flashes when it is lower than the alarm value, and the flashing frequency is 1 second per time, the red light flashes when it is higher than the alarm value, and the flashing frequency is 0.5 second per time. 5. When the real time data in the main interface is lower than the alarm value, the green value will be displayed, and if it exceeds the alarm value, the red value will be displayed..
