A2 Instrument Design
LCM plus measures transmissions of all transparent media. It operates with a halogen lamp
producing standard illuminant C and uses the 2° standard observer as defined by DIN-standard
5033. A reference beam path compensates measuring values modified by driftings of lamps and
temperatures during operation. Therefore, LCM plus provides an excellent long-term constancy
and reproducible measuring results. The universal cuvette compartment suitable for 50 x 10mm
square cuvettes and 11mm round glass cuvettes permits an optimum adaptation of LCM plus to the
measurement tasks.
In just one measurement, LCM plus evaluates by to the latest ISO-standards giving e.g. Iodine,
Hazen or Gardner values. The basical instrument includes one optional colour number with the
possibility of adding-on a random combination of colour numbers later or at once. These colour
systems are available: Iodine number, Hazen number, Gardner number, Saybolt number and ASTM
D 1500- number. To add-on more colour systems later, a program-module-box (bit-box) is
supplied. The description of this bit-box is given in chapter D6.
