Precautions

This refractometer is an electronic instrument – it can become damaged if dropped or handled in a rough manner.

The prism is made of optical glass and is susceptible to scratches – do not apply any rough or abrasive material and take care when cleaning the prism.

After each use, clean the prism & prism assembly with a soft cloth or tissue soaked in water and wipe off with a dry cloth or tissue.

Do not hold the refractometer under a stream of water from a faucet. Do not splash it with or dip it in water.

If the surface of the prism becomes coated with an oily solution or similar, it will repel test sample and

affect readings. If this occurs, the prism should be cleaned with a weakened detergent or similar solvent.

Do not leave instrument under direct sunlight or in a vehicle on a sunny day.

Do not use an instrument unless you have personal knowledge of calibration.

 

Automatic Temperature Compensation (ATC)

Automatic-temperature-compensation insure that concentration reading of aqueous (water-based) solution will be accurate with respect to the sample’s temperature. This digital refractometer is able to automatically correct for differences in the temperature of the sample to a reference temperature, usually 20. It is well know that substantially all materials expend when heated (become less dense) and contract when cooled (become more dense). The speed of light in a liquid increases with temperature, and the refractive index therefore decreases. Although this thermal effect is small for solids, the change in density for liquids is substantial. For example, the reading for a sucrose solution will change by approximately 0.5 Brix for each 10(5) change in temperature. So a 10 Brix solution read at 42(108) would read 8 Brix on a non-temperature compensated instrument. Many hand-held refractometers are not temperature compensated and require the user to manually take temperature measurements and apply a correction. Other hand-held refractometers offer only rudimentary compensation in the range of 18(65) to 35(95). This digital refractometer can automatically compensate for temperature differences within the range 5 to 40. For the most accurate possible readings the instrument, the ambient temperature and the fluid should be in equilibrium within this temperature range. When testing a sample with a temperature that deviates a great deal from the temperature of the instrument. It may be necessary to put the instrument and the fluid in the same environment for some time. A good rule is to wait approximately 30 minutes for each 10(5) difference in temperature in order to conduct measurement after keeping the instrument, fluid to be tested and environment in the same temperature.
