Specifications
Measuring Range: 0 - 28% Salinity
Minimum Scale Division: 0.2%
Automatic Temperature Compensation Range:
10 to 30°C
Dimensions: 30 x 40 x 170mm (1 x 1.5 x 6.5”)
Weight: 200g (7 oz)

Instrument Description
1. Prism
2. Cover Plate
3. Correcting Screw
4. Mirror Tube
5. Eyepiece (Adjusting ring of diopter)
Operating Instructions
1. Aim the front end of the refractometer towards the direction of a bright light
and adjust the Eyepiece until the reticule is clearly seen.
2. Open the Cover Plate and clean the surface of the Prism with the included
Cleaning Cloth.
3. Apply 1 - 2 drops of measuring solution, close the Cover Plate and press
lightly. Read the corresponding scale of light/dark boundary. The reading
is the percent of the salt content of the measured solution. The carved line
on the left of the scale indicates the specic gravity of the sodium chloride
liquor.
4. After measuring clean the measured solution off the Prism and Cover Plate
with a moist cotton cloth. Allow to air dry before storing.

Calibration
1. Open the cover plate & place 2-3 drops of distilled water onto the prism
surface, close the cover plate, press lightly & ensure the water spreads
evenly across the whole surface area without air bubbles or dry sections.
(wait 30seconds until the water adjusts to ambient temperature)
2. Hold towards light source & look into the eyepiece, if the boundary line
between the upper blue eld & the lower white eld is not located exactly on
the 0°C waterline, adjust the correcting screw until both lines meet.
3. Wipe the water from the prism with clean dry cloth & replace the rubber
correcting screw cover.
NOTE: under normal operating conditions the calibration only needs to be checked
periodically.
Maintenance
1. If the ambient temperature is not within the automatic temperature
compensation range (10 - 30°C) the instrument must be calibrated before
testing commences.
2. The prism must be cleaned thoroughly with a soft, clean damp cloth after
each use – failure to do so will result in inaccurate readings & possible long
term
damage
3. The instrument must be kept in a dry clean environment to prevent
condensation forming on the optical components
4. If used in accordance with the instructions & all warning are followed – the
optical performance will remain constant & the instrument will give many
years of reliable service.

Warning
1. DO NOT IMMERSE IN OR CLEAN WITH RUNNING WATER
2. THIS TOOL IS A PRECISON OPTICAL INSTRUMENT, IT REQUIRES
CAREFULL HANDLING & STORAGE
3. DO NOT DROP OR SUBJECT TO SHOCK AS DAMAGE MAY RESULT TO
THE MIRROR TUBE & OPTICAL COMPONENTS
4. DO NOT SCRATCH OR ATTEMPT TO MEASURE CORROSIVE CHEMICALS
AS DAMAGE MAY OCCUR TO THE PRISM’S COATING
