    SURFACE ROUGHNESS TESTER SRT-6200

    Quantity Order:
    Origin:
    China
    Pack. & Delivery:
    carton

    Specification :

    This instrument is compatible with four standards of
    ISO, DIN, ANSI and JIS and is widely used in production
    site to measure surface roughness of various
    machinery-processed parts, calculate corresponding
    parameters according to selected measuring conditions
    and clearly display all measurement parameters.
    When measuring the roughness of a surface, the
    sensor is placed on the surface and then uniformly
    slides along the surface by driving the mechanism
    inside the tester. The sensor gets the surface roughness
    by the sharp built-in probe. This roughness causes
    displacement of the probe which results in change of
    inductive amount of induction coils so as to generate
    analogue signal, which is in proportion to the surface
    roughness at output end of phase-sensitive rectifier.
    The exclusive DSP processes and calculates and then
    outputs the measurement results on LCD.
    * Very easy to operate
    * Multiple parameter measurement: Ra, Rz
    * Highly sophisticated inductance sensor
    * Built-in lithium ion rechargeable battery and control
    circuit with high capacity
    * Small in size, light in weight and easy to use
    * Can communicate with PC computer for statistics,
    printing and analysing by the optional cable and the
    software for RS232C interface.
    * Manual or automatic shut down. The tester can be
    switched off by pressing the Power key at any time.
    On the other hand, the tester will power itself off
    about 5 minutes after the last key operation.
