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.

The calibration and software-based adjustment options mean that the MD 100 is also suitable for use as a testing instrument. The tests are conducted using either Lovibond tablet reagents with long-term stability and a guaranteed minimum 5 or 10 year shelf life, VARIO powder reagents or using liquid reagents.

Scroll Memory (SM)

To avoid unnecessary scrolling for the required test method, the instrument memorizes the last method used before switching off the instrument. When the instrument is switched on again, the scroll list comes up with the last used test method first.

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)
