CR Radon Gas Instrument

We are certified radon measurement specialists by the National Radon Safety Board. 
We use a Rad-7 from Durridge Corp. A certified, radon laboratory, it provides on-site readings during the inspection.
As part of our inspection process, the Rad-7 is set up to take measurements during the inspection, giving an immediate read-out.  If levels appear elevated, or at the request of the client, the machine may be left for a 48 hour test. The conclusive result takes hourly measurements, with a high, low and standard deviation printout. It eliminates the inconvenient charcoal cannister tests which must be mailed away to a laboratory for processing and saves time.
