Meets EPA Performance Criteria of the CR protocol. Our electronic radon gas detector/monitor is a proven performer being in service since 1996. Used by inspectors, consultants and homeowners to monitor the radon gas levels in schools, offices and residences. It is a solid state continuous radon monitor which utilizes patented technology. At the heart of the device is a measurement circuit and pulse processing software which records alpha events on a photovoltaic sensor. Radon daughters create a spark when they come in contact with the potential across the collection dome and the photovoltaic sensor counts these pulses. The software equates pulse volume into pCi/L (Pico Curies per Liter) and then displays the information on the LED display. Follow this link for more technical info (will open in new window)
