7. Verifying Calibration and Calibration Certification
[1] Verifying Calibration
To ensure measurement accuracy, the refractometer should be zero set prior to use
each day. Periodic maintenance/service and calibration of your refractometer is
recommended. The frequency at which calibration is performed will depend on each
company's Standard Operating Procedures.
①Confirm that the prism is clean and free of scratches.
②Depending on the model, measure with purified water or a sucrose solution. Check that the boundary line is parallel to the
memory lines.
③Verify that the measurement value matches the expected value of the known calibration solution.
[2] Calibration Certification
Based on ISO quality management system, Calibration Certificates can be ordered for any ATAGO refractometer. HACCP or
GMP certification can also be provided at additional cost. Please contact an ATAGO distributor for more information.
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.
Note: A brix value expressed as a percentage (%) is equivalent to that value expressed in degrees Brix (°Brix).
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.
10. Repair and warranty
The MASTER-M 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.
Have the serial number of your refractometer available when asking about repair.
