DIY Nuclear Radiation Meter Circuit Board Kit Assembled Geiger Counter Radioactive Ray X//-Ray Radioactive Tester Radiation Tester with Buzzer

DIY Nuclear Radiation Meter Circuit Board Kit Assembled Geiger Counter Radioactive Ray X//-Ray Radioactive Tester Radiation Tester with Buzzer
Description:
This nuclear radiation Tester can Test x-ray, gamma rays, beta rays, and can perform radioactive dose Test on marble, antiques, jades, oversea shopping products, iodine 131, medical equipment and various unknown minerals for decoration.
Features:
1. Sound and light alarm
2. Support most Geiger tubes:M4011 can be installed directly, other models cannot be installed on the board, but the flying leads can also be used (digital multimeter measures the positive pole of the Geiger tube to the negative pole of the power supply, adjust the blue potentiometer until the multimeter shows DC 170 volts)
3. An external screen or pointer meter can be used as monitoring, the output signal is interrupt output, the waveform is the falling edge of the pulse, and the low level is valid.
4. The circuit structure is stable and the failure rate is extremely low
