1.1 General Safety Instructions
Liability
• This document does not claim to address all
safety issues associated with the use of the
instrument and samples. It is your responsibility
to establish health and safety practices and

described in the documentation. Anton Paar
GmbH is not liable for damages caused by
incorrect use of L-Rix 5000/5100/5200.
Installation and use
• L-Rix 5000/5100/5200 is not an explosion-proof
instrument and therefore must not be operated
in areas with risk of explosion.
• The installation procedure should only be car-
ried out by authorized personnel who are famil-
iar with the installation instructions.
• Do not use any accessories or spare parts other
than those supplied or approved by Anton Paar
GmbH (see Chapter 3 ).
• Make sure all operators are trained to use the
instrument safely and correctly before starting
any applicable operations.
• In case of damage or malfunction, do not con-
tinue operating L-Rix 5000/5100/5200. Do not
operate the instrument under conditions which
could result in damage to goods and/or injuries
and loss of life.
• Check L-Rix 5000/5100/5200 for chemical resis-
tance to the samples and cleaning agents.
• Use only approved cleaning agents. Follow
manufacturer's instructions for dosing and do
not overdose for environmental reasons. Do not
exceed manufacturer's recommendations for
cleaning temperatures (Typ. 50-70 °C) . One
hour cleaning per week is enough for the sen-
sors. Rinsing with hot water should only be done
once a day.
Maintenance and service
• The results delivered by L-Rix 5000/5100/5200
not only depend on the correct functioning of the
instrument, but also on various other factors.
We therefore recommend you have the results
checked (e.g. plausibility tested) by skilled per-
sonnel before consequential actions are taken
based on the results.
• Service and repair procedures may only be car-
ried out by authorized personnel or by Anton
Paar GmbH.
Disposal
• Concerning the disposal of L-Rix 5000/5100/
5200, observe the legal requirements in your
country.
Returns
• For repairs send the cleaned L-Rix 5000/5100/
5200 (instrument) to your Anton Paar represen-
tative. Only return the instrument together with
the filled out RMA (Return Material Authoriza-
tion) and the form "Safety Declaration for Instru-
ment Repairs". Please download the Safety
Declaration form from our website www.anton-
paar.com.
• Do not return instruments which are contami-
nated by radioactive materials, infectious agents
or other harmful substances that cause health
hazards.

1 Safety Instructions
6D32IB002EN-D
Precautions for highly inflammable samples
and cleaning agents
• Observe and adhere to your national safety reg-
ulations for handling the measured samples
(e.g. use of safety goggles, gloves, respiratory
protection etc.).
• Do not spill sample/cleaning agents or leave
their containers uncovered. Immediately remove
spilled sample/cleaning agents.
• Make sure that the setup location is sufficiently
ventilated. The environment of L-Rix 5000/5100/
5200 must be kept free of inflammable gases
and vapors.
• Supply a fire extinguisher.

2 Inline Refractometer - An Overview
L-Rix 5000/5100/5200 is an optical inline refracto-
meter for the determination of the refractive index
(RI) in liquids based on Snell’s law of refraction. It
can be immersed directly in the production liquid. It
continuously displays the refractive index (or con-
centrations) at process temperature allowing 24-
hour production control.
The process liquid flows past the sensor. The refrac-
tive index and temperature are measured simulta-
neously and displayed on the screen.
The inline refractive index measurement can be
used as a real-time predictive tool for the final con-
centration, whereby a quick and accurate response
is needed to optimize production.
The robust stainless steel construction of L-Rix
5000/5100/5200 meets all requirements of the pro-
cess environment and is fully CIP/SIP capable.
L-Rix 5000/5100/5200 has integrated self-
diagnosis.
The L-Rix Inline Refractometers are available as:
• L-Rix 5100/5200 Sensor
• L-Rix 5000 Transmitter
(=L-Rix 5100 Sensor + Pico 3000 Analog)
Features and Benefits:
• Maintenance free
• Never requires adjustment
• Long-life LED
• Hygienic design
• Full range sugar scale instrument
• No influence of potential stray lights
• Laboratory comparable refractive index mea-
surement
• Full CIP/SIP capability, reactivating quickly after
a brief time-out interval for cleaning
• Install and forget simplicity
• Compact and rugged design for industrial dura-
bility
• Longevity by hermetical sealing of optical com-
ponents
• Fulfills the NAMUR recommendation NE 107
(self-monitoring and diagnosis)
2.1 Measuring Principle
The L-Rix inline sensor determines the refractive in-
dex of liquids based on the critical angle measure-
ment as shown below. The refractive index is a
direct measure of the concentration. The measuring
prism serves as the interface between the L-Rix and
the sample liquid. The light source illuminates onto
the boundary layer between the prism and sample
liquid. Depending on the angle, some light rays will
be totally reflected, others only partially, with the
majority of the light refracted into the liquid. A CMOS
array detects the reflected light and measures the
critical angle. This angle is used to determine the re-
fractive index (specified as nD) and calculate the
concentration.
