Eccomum Simple Portable Nuclear Radiation Meter Circuit Board Kit Finish Assembled DIY Kit Household Geiger Counter Radioactive Ray X-Ray γ-Ray Iodine 131 Medicals Equipment Radiation Tester Dosimet

This simple nuclear radiation detector can detect x-rays gamma rays beta rays and can perform radioactive dose detection on marbles antiques jades iodine 131 medicals equipment and various unknown minerals for decoration. If you are looking for this product come and have a try it will not let you down. Features: Sound and alarm ways can better remind you give you a better use experience. This product uses an NE555 integrated circuit and peripheral electronic component to form an oscillator and transmits power to the diode voltage doubler circuit through inductive energy storage. The end of the voltage doubler circuit can output a high voltage of 400 volts for Geiger counters. Wide Applications: This nuclear radiation detector can detect x-rays gamma rays beta rays and can perform radioactive dose detection on marble antiques iodine 131 medicals equipment and various unknown minerals. 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 direct current 170 volts). An external screen or pointer meter can be used as monitoring the output signal is interrupt output the waveform is the falling edges of the pulse and the low level is valid. The circuit structure is stable and the failure rate is extremely low you can use it for your daily needs.
