SONO-WZ Concrete Sensor

SONO-WZ Concrete Sensor from IMKO, Germany, analyses water & cement in fresh concrete. It gives fast, accurate results within 1 or 2 minutes of testing onsite.  The sensor defines the water content and W/C-value of fresh concrete immediately. This gives an instant assessment of the quality of the concrete. The quality of fresh concrete is significant for the stability and lifetime of concrete buildings. Previously, to determine the quality of concrete, a sample had to be dried and then tested, a cumbersome and time-consuming process.
