Building materials moisture meter SONO-ES

for solidsfor bulk materialsby conductivity measurement

All traditional procedures to measure moisture in hardened concrete are strongly dependent on disturbance variables like temperature and volatile salinity. Long-term stability of many sensors like humidity sensors is also not guaranteed. In contrast to previous methods TRIME-TDR stands out by its non-destructive, accurate and long-term stable measurement technology. Applications and benefits • Continuous measurement of the moisture of concrete, rock, stone and masonry • The diameter of the probe with 22mm enables a simple installation vertically as well as horizontally up to installation depths of 2.5m • A retrofitting installation of the probe even in difficult to access areas of an existing building is possible • Purchase, storage, transport and use of the TRIME-TDR measurement technology are not subject to any administrative requirements • Measurements are largely independent of temperature and electrical conductivity • Guranteed long-term use without recalibration of sensors Type of installation 1 In the first step a relatively flat borehole is drilled with a 22mm special drill into up to 2m drilling depths. The borehole sensor T3/22 is completed watertightly sealed with casting compound in the borehole, so an intrusion of water is excluded. This guarantees a long-term operation of the probe. Before encapsulating test measurements with the T3/22 should be performed. It should be no dirt between the spring loaded measuring plates and the borehole wall. Benefits • Easy to implement 22mm drilling • Installation depth up to 2m • The probe T3/22 is completely watertight encapsulated
