8. Brix Scale
All refractometers are designed to measure the refractive index of a solution. The Brix scale is based on a
sucrose (sugar)and water solution. However, since most samples contain substances other than sugar - such
as salts, minerals and proteins - the Brix percentage represents the total concentration of all soluble solids in the
sample. For certain samples, such as cutting oils and other industrial fluids, a conversion chart from the Brix
percentage to the sample's total concentration may be necessary.
Automatic Sample Distribution (ASD): Place apporoximately 0.3mL of sample
on the front end (Figure ①)or the rear end (Figure ②)of the sample stage, and
tilt the refractometer slightly in the proper direction to allow the sample to move
over the prism. The sample liquid will spread evenly and the measurement
value can then be read more quickly and easily. By eliminating the steps of
lifting and closing the daylight plate when applying a sample, the operator can
save much time when having to measure many samples daily.
(This measuring method requires the sample to be low in viscosity.)
9. When moisture accumulates in the eyepiece
If the view of the scale and boundary line becomes obstructed by
moisture within the eyepiece, follow the instructions below for proper
cleaning:
①While holding the eyepiece toward you, turn the eyepiece counter-
clockwise until it can be removed.
②Gently wipe the two areas indicated by the arrows in the figure
with a clean, dry cloth to remove any moisture.
③Replace the eyepiece and secure by turning in a clock-wise direction.
Note: A brix value expressed as a percentage (％) is equivalent to that value expressed in degrees Brix (°Brix).

Check
Point
To ensure your refractometer continues to operate properly and look new for a long time!
When measuring samples with a high salt content, be sure to clean the refractometer by wiping the unit completely after each use,
especially the metal areas. The unit should be stored in the ATAGO storage box provided when not in use.
Never splash
water on the unit.
Have the serial number of your refractometer available when asking about repair.
The MASTER-T series are warranted for one year after the date of purchase against any manufacturer defect in materials or workmanship.
Prism and sample stage are excluded from the warranty. Any of the following events happening to the unit will void the warranty:
●Disassembled by anyone other than authorized service provider ●Immersed in liquid or dropped
●Misused, abused, or used/stored in improper ambient conditions
Service fees are applicable for repairs after the warranty period expires. Contact an authorized ATAGO Service Center or the
original seller for details.
