REFRACTOMETER
INTENDED USE:
determining the freezing point of ethylene glycol
•
aqueous solutions in cooling systems in cars,
trucks, etc.
determination of the freezing point of water
•
solutions of propylene glycol in cooling systems in
heating/solar installations
Determination of the electrolyte density in lead-acid
•
batteries, e.g. used in the automotive industry
determining the concentration of ADBLUE and the
•
freezing point of windscreen washer fluid
A refractometer is a sensitive optical instrument used
to test the freezing temperature of coolants and to
determine the quality of the electrolyte in lead-acid
batteries. The substances tested are hazardous to
health, so it is absolutely necessary to avoid contact of
the tested liquid with the skin, and for dosing the liquid
use only the enclosed pipette.
DESCRIPTION:
Prism
1.
Prism cover
2.
Calibration screw
3.
Handle
4.
Viewfinder focusing knob
5.
USE:
After lifting the prism cover (2), apply one or two drops
of the fluid under test with a pipette onto the glass
field of the refractometer (1). Wait about 30 seconds
until the temperature of the tested liquid and the
instrument equilibrate. Look into the viewfinder and
take a reading at the boundary between the dark and
light areas. On the left scale read the freezing point (in
degrees Celsius) for ethylene glycol, on the right for
propylene glycol, and on the middle scale the density
of the electrolyte (RECHARGE - means it needs to be
charged, and GOOD - does not need to be charged).
After each measurement the measuring field should
be carefully cleaned with a soft cloth.
Do not wash the instrument by flooding it with
water - flooded optics of the instrument will make its
further operation impossible.
ATTENTION!
The refractometer is a sensitive optical instrument and
only by taking all measurements gently you can be
sure of failure-free and long-lasting operation.
CALIBRATION:
You should calibrate the refractometer before first use
using distilled water at about 20°C.
To do this, lift the transparent prism cover (2) and
place one or two drops of water on the prism (1) with a
pipette. Then close the prism cover (2) carefully so that
no air bubbles form between the flap and the glass
field. Wait about 30 seconds for the water sample to
reach the same temperature as the instrument. Point
the end of the instrument with the prism towards the
light source and look into the viewfinder where you
can see the circular measuring field. The upper part of
the measuring field is dark and the lower part is light.
Using a screwdriver, turn the adjusting screw (3) (after
removing the rubber screw cover) until the boundary
line between the dark and bright fields runs along the
waterline marked WATERLINE.
