1. Introduction
This refractometer is an easy-to-use measuring instrument.
Please read the operating instructions before use to achieve an optimal
measurement result.
The refractometer is designed for fast and precise determination of concentrations
in liquids. Automatic temperature compensation is also included. The measuring
instrument will work reliably for many years if handled correctly. These instructions
apply to all digital refractometers listed under point 3.

4. General information
4.1 Intended use
5
The refractometer is a measuring instrument for determining the refractive index of
transparent substances in liquid or in some cases also in the solid state. It is used
to observe the behaviour of light as it passes from a prism with known properties
to the substance being tested.

Use of the refractometer for other purposes is contrary to its intended use and

may be hazardous. The manufacturer shall not be liable for any damages caused by
improper use.

4.2 Warranty
The warranty shall be void in the event of:
▸ Failure to observe the instructions in the operating manual
▸ Use for purposes other than those described
▸ Modifications or opening the device housing
▸ Mechanical damage and/or damage resulting from media, liquids, natural
wear and tear
5. Basic safety information
5.1 Follow the instructions in the operating manual
▸ Carefully read through the operating manual even if you have
prior experience with KERN refractometers.
▸ Every language version includes a non-authoritative translation.
The original German document is the definitive version.
5.2 Warning
▸ Do not let acids come into contact with skin or eyes. If acid comes into contact
with skin, flush with copious amounts of water. Shower if larger areas of skin are
affected.
▸ If acid comes into contact with eyes, keep the eyelid open and flush the eye with
running lukewarm water from the outer corner to the inner corner. Flush eyes for
at least 15 minutes. Then consult a doctor or ophthalmologist immediately.
▸ Thoroughly clean the refractometer after each use.
▸ The refractometer must not be exposed to extreme temperatures, high
mechanical stresses, strong direct sunlight or high humidity.

▸ This refractometer is not a toy. Keep out of reach of children.
▸ Make sure that you will not be hit by anything else while you are using the
refractometer, as this could cause serious eye injuries
6. supplied items
After unpacking and before using the device for the first time, check that all
listed parts have been supplied. Replace damaged or faulty parts immediately
and do not put them into operation.

7. Automatic temperature compensation
The refractive coefficient is temperature-dependent. Materials expand when they
are heated (their density decreases) and contract when they cool (their density
increases). The speed of light through a liquid increases with the temperature
and the refractive coefficient therefore decreases.
In solid substances this thermal effect has only a minor impact. In liquid
substances, however, the change in density is considerable. Automatic
