The SONO-WZ® is industry’s best portable fresh concrete moisture meter. This portable moisture analyzer provides precise measurement of water content to determine water/cement ratio in fresh concrete directly on-site!

The SONO-WZ® utilizes proprietary TRIME® technology developed by IMKO to revolutionize the field of miniaturized TDR technology specifically for moisture measurement. TRIME TDR technology creates a measurement field that penetrates deep into the measuring sample resulting in highly accurate and repeatable moisture measurement values.

Controlling the moisture content and the temperature of the new concrete can can increase the structural integrity of the concrete and make it more resistant to future cracking. Most important parameters are water content and the W/C-value to reach the desired quality.

If you are looking to measure moisture content in sand, gravel, grit, crushed stone, and other aggregates etc., then check out our HD2® Portable Aggregate Moisture Meter.

With current conventional methods a sample has to be dried in an oven or a kiln first before determining water content as well as the W/C-value. This process is neither consistent nor accurate as the results depend on the characteristics of the sample under test. For example, any inconsistency in the stone size in your sample can throw off your measurements by 10-20% or higher! This is because larger stones absorb higher moisture content, and presence of even one large stone in your sample will indicate a higher moisture content in your mix that there actually is. Furthermore, the drying methods are long and cumbersome and each measurement takes up to 30 minutes.

The SONO-WZ® is an easy and convenient method to measure concrete moisture in under 2 minutes!

The water / liquid proportions measured by SONO-WZ:

In principle, SONO-WZ® measures the same proportions of water as the kiln drying method.

›  The effective water in the concrete mix is the water which is considered for the w/c ratio. This water is the target value to be determined with SONO-WZ.
›  Part of the core water, water that is sucked up by the aggregates, whereby 1/3 of the core water is captured by SONO-WZ. Depending on the type of rock, the core water can be 2 up to > 50 liters per m3.
›  Additives that behave like water are also measure captured by SONO-WZ, which must be taken into account.

Main Features:

› Reduce lab work with this user friendly and intelligent device
› Measurements available in both Liter/m3 and Pounds/cubic yard
› Determine water content of fresh concrete directly on-site, in a matter of minutes
› Enter the weight of the cement and get direct display of the w/c ratio
› Adjustable for additives such as self-compacting concrete, fair faced concrete, light-weight concrete, heavy concrete, etc.
› Achieve representative measurements with automatic averaging of data points
› Enables correlation of recipe parameters such as cement content and slump of fresh concrete
› Accurate real-time averaged moisture values at a rate of 4 per second
