MyGeiger ver.3 PRO DIY Geiger Counter Kit

MyGeiger ver.3 PRO DIY Geiger Counter kit is intended for enthusiasts, a physics students, teachers and researchers engages in radiation study. It fit hobby projects as well as environment or laboratory test. MyGeiger ver.3. is compatible with wide range of 400V and 500V Geiger tubes; it has flexible options for calibration that allows you to adjust your counter for different GM tubes.

The kit has re-designed efficient high voltage with enlarged output power, faster microprocessor with updated and enhanced software, setup menu, USB CPM / CPS logging, faster lithium charger, reduced power consumption, power safe sleep mode and comfortable big buttons for control. Now it got the ability to operate in radiation field higher than 1500uSv/h with SBM-20 where the tube operates at the maximum possible count rate.

The device has two working modes: Gamma Dose Rate Meter and Average CPS counter. In averaging mode it can be switched to work as a digital counter for an external scintillation probe as soon as the input signal from the probe fit requirements of the pulse polarity and amplitude.

Electronic board of the kit comes fully soldered and tested, you only need to add your favorite GM tube and lithium battery.

MyGeiger has lifetime technical support. If you want to keep your firmware version up to date then you are welcome to contact us for getting hex file update.

HV Driver with Signal Buffer for Geiger TubeSome projects requires an additional external GM probe for the dosimeter. We offer a HV Geiger Probe Module addon for building high performance external GM pancake probe. The module is fully compatible with MyGeiger kit and with others digital DIY Geiger Projects. The addon module can be used for building GM probe with long signal cable up to several meters. High voltage for tube is generated locally on the module and can be adjusted in range of 400V-500V. Tube's logic level digital signal output is buffered and can drive long signal cable. An audio cable with Left+Right and GND conductors can be used to connect the probe to Geiger Counter project. L+R intended for 3.7V VDD and TTL signal line when GND have to be shield conductor of the cable. 
DIY Multi Channel Analyzer for Gamma Spectroscopy

Gamma Viewer MCA - DIY Multi Channel Analyzer for amateur Gamma Spectroscopy. The module is assembled board based on PIC18 microcontroller. It allows to view and collect gamma spectum instantly without a computer and safe spectra on micro SD card. Display can be set for 128-1024 channels. The 10bit ADC of the microprocessor allows to measure pulse amplitude precisionly, but you need to setup a compatible pulse preamplier on your PMT probe. The MCA is recommended for count rate speed < 1000CPS

The analog circuit and software require calibration, so it's better to have an oscilloscope and some previous experience to deal with PMT tubes in spectroscopy subject. With correct setup you can get FWHM resolution <7%

We supply electrical circuit for compatible with the MCA pulse amplifier that you'll need to solder on your PMT. Optionally you are welcome to use our automatic bundle purchase discount and pick up ready pulse amplifier module from store stock. Check the DIY Gamma Spectroscopy category for different modules and photomultiplier drivers.
