Environment of Use Indoor/Outdoor
Type of Instrument Gas Analyzer
The instrument measures: Radon in soil

RAD7 can be used for both short-term or long-term measurements. The unit is based on a semiconductor detector measuring radon daughters collected with a strong electric field. RAD7 is capable of dissolving the energy of various radon isotopes radon (Radon-222) and toron (Radon-220).

After each measurement cycle is completed, a printout with the measurement result comes from the wireless included printer.
After the measurement is completed, the results can be sent to a PC for post-analysis and report editing to the end customer.
A Capture Transfer Software is included free of charge and can be automatically translated into multiple languages.
With the required accessories, RAD7 can also be employed to analyze radon in water and to conduct soil surveys.

The price also includes a half-day training online.
