Introduction
The Lovibond® Model Fx instrument is a high-precision spectrophotometer, which has been designed for
the objective colour measurement of clear liquids. It is an easy to use, automatic instrument which
overcomes the subjectivity of visual methods. The menu system guides operators through the selection of
operating parameters. Thereafter, measurements are initiated by just a single key press and take less than
5 seconds to complete. The Lovibond® Model Fx instrument is a rugged spectrophotometer with
aluminium housing that has been coated with a hard powder coat finish to provide the best protection
possible. The Lovibond® Model Fx has been designed to function as a QC instrument within the laboratory
or on 24-hour operation in a process control environment.
The Lovibond® Model Fx instrument operates as a stand-alone colorimeter containing a standardised light
source and collimator, sample chamber, light detector, spectrometer and processor board.
Colour scales
The Lovibond® Model Fx instrument has been designed to meet the colour analysis requirements of light
transmitting samples such as edible oils. The Lovibond®Model Fx provides colour data according to the
Lovibond®RYBN, AOCS-Tintometer®colour, Chlorophyll and β-Carotene colour spaces and scales.

Installation
Place the instrument on a bench near a mains voltage supply which is free from excessive voltage
fluctuations. The external power supply is auto voltage sensing, so no setting up is required for local
voltages.
Do not operate the instrument in an atmosphere containing explosive gases.
Plug in the mains lead and switch on. The display will indicate that the instrument is on.
If the instrument has been in a cold environment prior to setting up, allow the instrument to warm up to
room temperature and ensure that all condensation has dissipated before switching on.
Always ensure that there is sufficient free space around the instrument to maintain a constant flow of air.
