    Muffle Furnace to Test Ash Content

    The Testronix muffle furnace is used to determine the ash content of a specimen.

    The percentage of ash in a material gives important insights into the properties of the substance.

    The Testronix muffle furnace is specially designed as per IS & ASTM Standards.

    It finds wide application in various fields such as Medical research, agricultural, industrial, metal treatment, rubber & wool industries, metal treatment, ash determination.

    The percentage of ash is calculated as the index of added mineral matter or loading.

    A known weight of the specimen is burnt, the ash is weighed, and the percentage is calculated.

    The Testronix Muffle furnace is finished in Autumn Gray & Blue combination painting to give it a corrosion resistant finish.

    The Instrument comes complete with Instruction Manual; Electrical Wiring Diagram & Calibration Certificate traceable to NABL approved Labs.

    Optional Accessories:

    • Digital Timer
    • PID Controller with Computer/printer interface.

    Useful for :

    • Foam And Gaskets
    • Wood & Laminates
    • Polymers

    Muffle Furnace is a unique test cabinet designed to detect the percentage of ash content in a particular test specimen like rubber, elastomers.

    It is Bench top model and is used to evaluate the amount of inorganic compound in a test material.
