Measuring 5 inches in length, the new Rapid RH Long Reader makes it easier than ever to use Wagner’s Rapid RH method for relative humidity measurement in concrete slabs, the company said.
As with the original Short Reader, the Long Reader is used to read the Rapid RH Smart Sensors. It was specifically designed for measuring the relative humidity in slabs thicker than 4 inches. However, its longer length makes it ideal for any test depth. ASTM F 2170 states that the relative humidity of a slab must be measured at 40% of the depth of the slab. With the Rapid RH Long Reader, measuring the relative humidity just got easier, no matter how thick the slab.
