3. General information
3.1 Intended use
The refractometer is a measuring instrument for determining the refractive index of
transparent substances in the liquid or 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.
3.2 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
4. Basic safety information
4.1 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.
4.2 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 aer 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
▸ The rubber eyeshade may cause irritation when in prolonged contact with the
skin. If this happens, consult your doctor.
▸ Do not touch the lenses with your fingers.
6. Before the first use
Remove the protective film
(
if present
)
from the prism surface
[

]
and check that
the rubber eye-cup
[
4
]
is fitted correctly.
7. Use/measurement
The refractometer can be used to quickly and accurately determine the refractive
index of transparent substances, liquid or solid ones. To ensure correct measure-
ment, the measuring device should be adjusted before measurements are carried
out. Please make sure your hands are dry before handling the measuring device.
5. Supplied items
Aer 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.
▸ Refractometer
▸ Storage box
▸ Pipette
▸ Adjustment tool
▸ Cleaning cloth
▸
Calibration block + Contact Clove oil liquid ( )
!
Avoid bringing the supplied contact liquid (clove oil) into contact with the prism
cover [1]. Even the smallest amounts of clove oil will damage the material of the
cover and lead to its opacification.
Therefore, pay big attention to this aspect while carrying out the adjustment of the refractometer
described below.
If still there is accidentally contact between clove oil and the prism cover, it would not affect
subsequent measurement operations even when high opacification occurs.
Important!
