    The MD 100 uses high quality interference filters with long-life LEDs as a light source without any moving parts in a transparency sample chamber. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions, and safe handling.

    Calibration certificate
    Beside the “Certificate of Compliance” which is supplied with the MD 100, calibration certificates are available at cost on request. Calibration certificates are individually supplied per instrument and per method. The Calibration Certificate has to be ordered together with the new instrument and cannot be delivered at a later stage.

    N.I.S.T Traceability
    The instrument has a factory calibration, which is related to international standards which are not N.I.S.T traceable. The instrument may be calibrated by the user in a “user calibration mode” with N.I.S.T traceable standards.
    (N.I.S.T. = National Institute of Standards and Technology)

    Optics LEDs, interference filters (IF) and photo sensor in transparent sample chamber. Depending on the version, up to 3 different interference filters are used.
