Flir Extech RF10 User's Guide

To calibrate the RF10 Refractometer, place a few drops of distilled water on the prism, close the cover plate, and adjust the calibration screw until the boundary line aligns with the zero scale.
Use a soft, lint-free cloth moistened with distilled water to gently clean the prism after each use. Avoid using alcohol or other solvents as they may damage the prism.
The RF10 Refractometer is designed primarily for measuring the concentration of sugar solutions. For alcohol concentration, a specialized refractometer calibrated for alcohol is recommended.
Ensure the refractometer is properly calibrated, clean the prism thoroughly, and make sure the sample temperature is consistent with the operating temperature range of the device.
It is recommended to calibrate the refractometer before each use to ensure accurate readings, especially when measuring different samples or if the device has been subjected to temperature changes.
The RF10 Refractometer features an automatic temperature compensation (ATC) range from 10°C to 30°C, ensuring accurate readings within this temperature range.
Yes, the RF10 Refractometer can measure the sugar concentration in honey, providing a Brix percentage which is useful for assessing honey quality.
Regularly clean the prism, store the refractometer in a protective case away from direct sunlight and extreme temperatures, and avoid dropping or shaking the device.
Typically, only 2-3 drops of the sample are needed to cover the prism surface adequately for an accurate measurement.
The RF10 Refractometer is designed for liquid samples. Non-liquid samples need to be dissolved in a liquid that does not interfere with the measurement for accurate readings.
