Product Details

This unit is designed for the experimental determination of the thermal conductivity of various non-corrosive liquids and non-flammable gases. It provides a precise method for investigating conductive heat transfer through fluid samples under controlled conditions, preventing convection to isolate pure conduction. The apparatus features a heated central plug and a water-cooled jacket, creating a narrow radial gap where the test fluid is placed. This design ensures a thin laminar film that suppresses natural convection. Integral thermocouple sensors measure temperatures on both sides of the fluid layer, while the heat input is accurately controlled and measured. The unit is calibrated using air to account for parasitic heat losses and can be easily disassembled for cleaning with a single bolt and replaceable O-ring seals. Its primary application is in educational and research laboratories for studying thermal properties of fluids such as oils and glycerine. The key benefit is its ability to provide accurate, reproducible measurements of thermal conductivity, offering students hands-on experience with fundamental heat transfer principles and the methodology for characterizing fluid properties. The simple yet effective design allows for quick sample changes and straightforward operation.
