    thermal conductivity The MP-2 is an advanced meter with unique selection of transient thermal conductivity sensors for a variety of applications, with a focus on primary measurements. The transient thermal conductivity sensors share similar principles of operation. The sensor wire is heated using a constant current source (q), and the temperature rise is recorded by monitoring the change in electrical resistance of the wire (TPS and THW) or by a resistance temperature detector device (TLS). For samples of high thermal conductivity, the lower the slope; for samples of low thermal conductivity, the higher the slope.

    For convenience, the auto-testing function can be programmed on-board or with the MP-2 Windows utility software. Additional on-board, and utility features include the ability to review, save or delete, and export results to Excel. To maximize portability, power can be supplied by battery or USB cable. Informative screen icons keep users informed about power status and testing progress.

        Thermal Conductivity of cutting fluids with the Transient Hot Wire

        Depending on the context and on which type of cutting fluid is being considered, these fluids may be referred to as cutting fluid, cutting oil, cutting compound, coolant, or lubricant. The main purposes of these fluids are to keep the object being cut at a stable temperature, maximize the life of the cutting tip, and prevent rust on machine parts and cutters.
