Measuring, signaling and checking (supervision) apparatus and instruments

Building construction, namely leakage location in buildings, particularly flat roofs, brick works and thermal insulations; on high-level tanks, swimming pools, disposal sites, in water-conducting ducts, long-distance heating ducts, by means of visual leakage location, electronic leakage location, flue gas leakage location, tracer gas leakage location, infrared thermography, flat roof insulation layer drying; determination of skeleton layers and concealed building construction elements particularly by infrared measurement
