Product details (archived)

The information below is retained for reference only. This item is discontinued and cannot be ordered.

This electronic radon 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. Since there is no offal from a pulse event, this measurement device requires no periodic calibration.

Results will display in approx 48 hrs on a numeric digital LED display (range 0 - 999)
Shows the level of radon gas in pCi/L on a short-term or long-term basis
2 modes of measurement - long & short term
Alarm sounds if the long-term average reaches 4 pCi/L or greater (can be silenced)
Samples air continuously; display updated every hour.
Self-test every 24 hours with an error code displayed if failure.
