HOW TO USE THE HANDHELD REFRACTOMETER
Handheld refractometers can be used to find
the freezin point of antifreeze fluids (water/
propylene lycol, water/ethylene lycol
solutions) or windscreen cleanin liquids or
the specific ravity of battery fluids.
Ope ation
Focusing
a. Point the instrument towards a li ht source;
look into the eyepiece and adjust the
dioptre rin to focus on the raded scale.
Calib ation
b. Open the cover plate, put a few drops of
common water on the blue lass prism
usin the plastic dropper (supplied), close
the plate and press it li htly to spread the
water evenly over the surface of the prism
without leavin air bubbles or dry areas.
c. Leave the water on the prism for about 30 seconds to let it adapt to the temperature of the refractometer.
d. Hold the instrument towards the li ht and look into the eyepiece. You should see a raduated circle with a dark
upper part and a li ht lower part.
e. If the border between the dark part and the li ht part does not fall on the zero of the raded scale (marked
"WATERLINE"), the instrument needs to be calibrated.
f. Take off the protective cap and, usin the screwdriver supplied, adjust the calibration screw so that the dividin
line between the dark and the li ht parts in the eyepiece coincides with the zero on the raded scale marked
"WATERLINE".
Note: The ze o setting and the subsequent eadings should be done at the same tempe atu e. If the e a e
conside able changes in tempe atu e, eset the ze o eve y 30 minutes.
Readings
g. Open the cover plate, clean the surface of the prism with a soft cloth (supplied) and put a few drops of the
solution to be tested on the blue lass prism usin the plastic dropper. Close the plate and press it li htly to
spread the solution evenly over the surface of the prism without leavin air bubbles or dry areas.
h. Lookin throu h the eyepiece, find the dividin line between the dark and li ht parts and read the
correspondin value on the raded scale.
With this procedure you can find the freezin point of water/ lycol solutions or windscreen fluids or the specific
ravity of battery fluids.
P ecautions and maintenance
- Do not expose the instrument to humidity and do not put it in water — althou h it is protected a ainst splashes
it is not waterti ht. If the eyepiece fo s up the instrument has been infiltrated by water.
- Do not use this instrument to test abrasive or corrosive substances that mi ht dama e the prism’s coatin .
- Clean the instrument after every readin usin the cloth supplied. If the surface of the prism appears dirty
because it was improperly dried, clean it with a cloth soaked in alcohol. If the prism is not re ularly cleaned the
results will be inaccurate and the prism’s coatin risks bein dama ed.
- This is an optical instrument. Handle it with care to avoid dama in the optics and casin .
Note: Although the inst ument’s eadings do not depend on tempe atu e, the g eatest accu acy is
achieved at an ave age tempe atu e of 20°C.

HOW TO USE THE PRESSURE GAUGE
This instrument lets you check the initial pressure in the
expansion vessel.
The measurin ran e is 0 to 4.5 bar.
The initial pressure in vessels normally used in the heatin
sector is 1.5 bar (in the factory); in solar installations the initial
pressure varies from 2.5 to 3 bar.
However, accurate adjustments can be performed based on the
installation desi n.
This pressure au e can also be used to check the tyre
pressure on cars, motorcycles or other vehicles.
Before usin the instrument make sure the pointer is on 0.5 bar. If it isn’t, push the metal button at the top left of
the instrument. This will brin the pointer to its startin position. Take the measurement and then press the metal
button a ain.
HOW TO USE THE CLINOMETER COMPASS
Use the clinometer compass to check the orientation and
inclination of flat-plate solar collectors.
Ideally, solar collectors should be installed facin south.

HOW TO USE THE LITMUS PAPER
a. Briefly dip a strip of litmus paper in a sample of thermal fluid. If the colour does not
stabilize immediately, leave the strip in the fluid until the colour remains stable.
b. Take the strip out and compare the colour of the two se ments on the strip with the chart
printed on the packa e.
c. After washin with a suitable cleanin product, measure the pH of both the mains water and the final rinse
water. MAKE SURE THE pH IS THE SAME.
