Care and Handling

Please note that Refractix is an optical device. To
maintain the device, clean the Sample Measurement
Surface and the Sample Well after each sample.
Always store the device with the Sample Measurement
Surface and Sample Well clean and dry.

Principle of Operation

As a digital refractometer, Refractix has been designed
to measure the refractive index of the sample and use
that to determine the temperature compensated result
in the selected scale.
Temperature Compensation (TC) corrects
measurements over a range of temperatures. Samples
measured over the temperature range of 10°C to
40°C (50°F to 104°F) are corrected to the reference
temperature of the selected scale (typically 20°C).
Temperature Compensation is necessary because
refractive index varies inversely with temperature. As
the temperature of the sample increases, the refractive
index will fall; as the temperature of the sample
decreases, the refractive index will rise.
