    Proceq's Equotip 550 Portable Rockwell and Leeb D hardness tester tests on-site heavy, large or installed parts and scratch-sensitive, polished and thin parts. This model will also work with UCI testing but you need to purchase an additional probe for that application.

    Features on-screen feedback which reduces measurement inaccuracies which can be caused by human error. The Proceq Equoptip 550 includes ready-to-go reports through powerful built-in reporting. Extremely durable touchscreen with enhanced software features and analysis functions.


    Equotip 550 Portable Leeb D and Rockwell Hardness Tester takes advantage of a new generation full color, dual processor Touchscreen Unit with enhanced software capabilities. The instrument offers a unique range of functions which ultimately help speed up on-site and laboratory inspections and analysis.

    Leeb D Features:

    Wide Measurement Range

    Leeb D impact devices are best suited for on-site testing of heavy, large or already installed parts.

    Broad Hardness Scales Coverage

    The measurements are automatically converted to all common hardness scales (HV, HB, HRC, HRB, HRA, HS) as required.

    Impact Devices & Accessories

    Proceq offers a wide variety of impact devices along with support rings to serve most hardness testing requirements.

    Test Blocks Portfolio

    Extensive range of precise hardness test blocks available for each impact device with different hardness levels for regular verification.

    Rockwell Features:

    Specially For Thin Parts

    Particularly suited for scratch sensitive and polished parts or on thin parts, profiles and pipes. The required minimum thickness for a reliable hardness reading is ten times the indentation depth. For the mass there is no minimum requirement.

    Broad Hardness Scales Coverage

    Measurements in HRC and HV with automatic integrated conversions to HB, HRA, HRB and many more common scales in compliance to ASTM E140 and ISO 18265.

    Suits Various Sample Geometries

    Unique measuring clamp and support feet are available for the probe allowing tests to be carried out on various geometries.

    For Any Environment

    The Equotip 550 Portable Rockwell can be utilized for on-site, factory and lab environment with almost no limitation.
