Unassembled Geiger Counters Kit DIY Geiger Counter Module Tube Tube Nuclear Radiation Detector Radiation Meter

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 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 Basic parameter: Geiger Tube Model: M4011 Type-C interface supply 5V1A consumption current: 20mA Dimensions: 61 x 92 mm Weight: about 40g Tube M4011 Specification: Diameter: Φ10±0.5mm length: 90±2mm Starting voltage: more than the 350V Recommended working voltage: 380V Minimum ping length: 80V Maximum ping slope: 10%/80V Extreme working voltage: 550V Maximum background count rate: 25 times / min Lifetime: more than the 1 x 109 pulses Style:A Unassembled Colour:black Material:plastic Package Contents: 1 * Radiation Detector Kit Only the above package content other products are not included.
