Radon Scout Plus

Click here for our Scout Plus Data Sheet

The Radon Scout and the Radon Scout PLUS (with display) are accurate, rugged and easy-to-use continuous radon monitors for professional use. The Scout is well-suited for both short-term and long-term measurement of radon gas. It is an ideal radon data logger for both radon screening and for mitigation work.

The Scout is used with a computer (XP, Vista, Windows 7 and 8) for data retrieval and analysis


using the supplied Radon Vision Software. Except for the RUN/STOP switch, it has no user controls. All setup, measurement and data transfer functions are handled by your computer using the Radon Vision Software.

The Scout does not need line power. It will operate more than 90 days on fresh alkaline batteries.


  • Radon Testing:
    Accurately measure radon gas levels. Determine if radon levels are above or below recommended guidelines. In a radon inspection at a school or commercial building, measure radon during occupied and unoccupied portions of the day. You can quickly determine the relation between the average radon level and the radon present during occupied times.

  • Radon Mitigation:
    As the mitigation job progresses, monitor indoor radon levels to suggest mitigation strategy. Measure hourly radon levels during the full time that you are on-site, and for two days after completion. Where radon levels are high, you can select a shorter integration time such as 15 minutes, with the Radon Scout PLUS. Analysis is fast and easy with the Radon Vision software. Select areas of interest (AOI) at the beginning, at different stages during the remediation and at completion to verify the mitigation’s effectiveness.

The Scout uses a solid state alpha decay sensor for radon gas that is not affected by temperature, humidity, radon daughters, air currents or gamma radiation levels to ensure accurate and repeatable results. It uses instrument-grade sensors to continually record environmental parameters. This helps ensure test validity and helps in interpreting the results.

AC Adapter

AC Adapter
When using the AC adapter with the Scout Plus, measurement will continue, uninterrupted, using the D-cell batteries, without any data loss, if the line power is interrupted.
If the batteries are allowed to discharge, measurement will stop but no collected data will be lost.

Tamper Resistant Carry Case Tamper Resistant Carry Case
We recommend using the carry case for deployment, transport and storage
9-pin Serial Cable 9-pin Serial Cable
USB Adapter USB Adapter

Data Security
You cannot loose data by turning off or by letting the batteries run down. The data memory can only be cleared using the Radon Vision software.
