This item includes a TOOL-081 USB data cable and GQ Geiger Counter Logger software for generic Geiger Counter (Geiger Counter is not included) This software works on most of old and new designed Geiger Counter. The GQ GMC Pro software is designed by GQ Electronics LLC, USA. It is designed to be a generic and convenient Windows based data logger for traditional Geiger counter. The software takes analog radiation pulses/clicks, converte it into digital signal and then process it. The USB data cable is used to connect between Geiger counter audio port and computer USB port. If the Geiger counter has no audio.speaker output port, then a simple audio adapter is needed. such as CDV-700 Software features Software update data display in real-time, as long as the radiation pulses been detected...

A great way to measure and log radioactivity! Watch as background levels fluctuate over the course of a weekend, or bring objects up to the sensor to see if they are emitting more than background. Compact G-M tube sensor plugs unto your computer's USB port. Intuitive software allows monitoring of BETA and GAMMA radiation levels right away and shows graphically how the levels are changing over time. Data is collected every 3 seconds and is date and time stamped. Display as CPM, mR/hr, or uSv/hr. Averaging time is selectable from 15 seconds to 10 minutes. No batteries or external power required. Audible event beep (can be disabled in software). There is even an audible alarm which you can set to go off at any level. Includes software CD and cable. Easy set-up. 1 year warranty. Made in USA...

The International Medcom CRM-100 is a hand-held radiation detector that detects potentially harmful ionizing alpha and beta particles, and gamma and x-ray radiation, and features an accumulated total timer function, a Geiger-Mueller (G-M) tube, and LCD digital display of milliroentgens (mR) per hour (mR/hr), counts per minute (CPM), microSieverts (μSv) per hour (μSv/hr), or counts per second (CPS). This radiation detector has the ability to detect levels of the four main types of ionizing alpha and beta particles, and gamma rays and x-rays over automatic operational ranges. It is optimized to detect small changes (low levels) in radiation levels and to have high sensitivity to many common radionuclides. The CRM-100 features a 4-digit LCD digital display that updates every three seconds... Less
