The third edition of MyGeiger DIY Geiger Counter Kit. MyGeiger ver.3.00 PRO is intended for measuring gamma radiation dose rate and for precision average CPS counting. The device was build for enthusiasts, a physics students, teachers and researchers engages in radiation study. It fit hobby projects as well as environment or laboratory test. The kit is compatible with wide range of 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, USB CPM / CPS
logging, faster lithium charger, reduced power consumption and
comfortable controls. Now it got the ability to operate in radiation
field higher than 1500uSv/h.
