Mainly used for
Used to measure the freezing point of ethylene glycol
as base, while measuring the freezing point of ethylene
glycol and measuring the weight of battery solution.
Only a few drops of ethylene glycol on the prism are
required for measurement, and then the freezing point
of ethylene glycol antifreeze can be read by observation.

Product Calibration Steps
Note: Before testing, the tester needs
to be corrected!
Step 1: Take one or two drops of distilled water or
pure water droplets and cover the surface of
the prism.
Step 2: Adjust the correction button until the blue-
white junction line coincides with the 0C
benchmark line

Method of use of products
1, lift the cover plate with a soft velvet cloth to
clean the cover plate and Prism surface.
2, the liquid to be measured with a straw on the
surface of the prism, close the cover plate gently
press, the freezing point tester to the bright place,
rotating the eyepiece to make the field of view
engraved lines clear, read the light and dark
dividing line in the division board The value on
the corresponding ruler can be
Use caveats
Please read the instructions carefully when
using the instrument
1. When measuring methanol solution, be careful not to spill on the
human body so as not to damage the body after the test carefully
wipe the instrument.
2. After use, it is forbidden to use tap water to wash directly to
avoid entering the optical system.
3. Avoid falling and other strong impact on the instrument or its
large external force
