High-Temperature Contact Angle Analyzer
The GFT uses a high-temperature transmission projection system to monitor wetting, contact-angle behavior, and profile changes in metals, inorganic compounds, and mixtures during sintering, softening, melting, and liquefaction. It records specimen images with associated temperature and height data for surface-tension and wetting-angle calculations.

Product Description
A CCD camera displays the specimen on a computer screen and records profile changes during programmed heating. The instrument uses a molybdenum–rhodium wire furnace to 1,700 °C; molybdenum wire can reach 1,750 °C under a protective atmosphere. Temperature control uses a B-type thermocouple and programmed or manual control.
The imaging system includes a USB2.0 digital CCD, microscope, lens, manually adjusted focus, and adjustable LED monochromatic cold light. Overtemperature and overcurrent protection are included.
