    Other tension ranges available on request.
    Other measuring units available, such as g or kg
    * SCHMIDT calibration material depending on tension range and roller width
    ** Outside dimensions of front plate

    Important for your order: Please specify model and roller width!
    Small dual-flanged outer guide rollers are standard. All 3 rollers can be equipped with one flange, if the material to be measured is wider than the rollers. Please request when you order.

    Calibration to customized material:
    If process material differs significantly from the SCHMIDT calibration material in diameter, rigidity or shape, special calibration using customer supplied samples is recommended. For this purpose a material sample of about 5 m should be supplied.
