The Next Generation in Relative Humidity Testing for Concrete in Floors

Spotlight

Wagner Electronics and the CTLGroup have joined forces to develop a revolutionary new concrete moisture detection device. The Rapid RH® is a fast, accurate, relative humidity (RH) probe that significantly decreases the time it takes to measure moisture in concrete floors. The Rapid RH® revolutionizes concrete floor testing by combining a moisture sensor, power supply, and display all in one small device.

This rugged, low-cost instrument allows general contractors, inspectors, and flooring professionals to quickly get accurate floor moisture and temperature readings. The Rapid RH® eliminates guesswork, messy testing methods, is disposable and can be left in the testing area. The Rapid RH® fits level with the concrete, preventing damage to the probe.

Simple to Use, Easy to Install

The Rapid RH® is easy to install and fits level with the testing area preventing damage to the probe. With the push of a button the Rapid RH® liquid crystal display gives you an accurate RH and temperature reading.

How the Rapid RH® Probe and Moisture Test Works

  1. Drill the hole to the desired depth in the concrete to be tested using a rotary hammer drill and the special countersink drill bit provided in the kit.
  2. Remove drilling debris in the hole using the special brush that is provided in the kit and a vacuum cleaner.
  3. Insert Rapid RH® probe into the hole and press downward. Allow probe to stabilize and record the RH.
