Our professional Continuous Radon Monitor is classified as a Continuous Radon Monitor (CRM) testing device, and has been evaluated and accepted by the US EPA for use in real estate transaction testing.
The Model 91027 provides both a digital display of the measured value as well as a report that may be obtained from either a printer or a computer. PC software, suitable for printing reports, is included with the instrument. A compact printer (P/N 020030) that plugs into the 91027 Monitor is available if an on-site report is required. (Data is stored in the Radon Monitor and can be printed at a later time.)
The Model 91027 is operated using line power (110 VAC). The instrument contains a 9 volt battery which provides backup power in the event of a power outage during a test. The Professional Continuous Radon Monitor employs internal sensors to detect and report movement during a test. The testing is not interrupted if tampering is detected, but the tampering is noted on the final report. The Model 91027 does not contain any replaceable or “consumable” parts. The instrument is completely reusable; simply clear the memory and it is ready for a new test.
