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

[

]

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 liquid ( )Clove oil

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!
