The Heating Microscope, Optical Fleximeter and Horizontal Optical Dilatometer Misura® HSML-FLEX-ODLT is an incomparable combination of three instruments ideal for studying the melting/ flattening, dilatometric and flexural behaviour of materials undergoing real industrial firing cycles. It represents a valid solution to study the physical behaviour of materials during a firing treatment, to carry out no contact bending dilatometric measurements, having all the required instruments in only one. Considering also that all the Misura® instruments are managed by a unique software, it is thus possible to obtain a complete characterization of the evaluated materials
