Flir Extech RF30 User's Guide

To calibrate the RF30 refractometer, ensure it is at room temperature. Place a couple of drops of distilled water on the prism, close the cover plate, and look through the eyepiece. Adjust the calibration screw until the boundary line aligns with the zero mark on the scale.
Clean the prism with a soft, lint-free cloth. For stubborn residues, use a mild soap solution and rinse with distilled water. Avoid using harsh chemicals or abrasive materials that could damage the prism.
Inaccurate readings can result from improper calibration, a dirty prism, or temperature variations. Ensure the device is correctly calibrated, the prism is clean, and the sample and refractometer are at the same temperature.
Yes, the RF30 Refractometer can measure the sugar content in beverages. It provides Brix readings, which indicate the sugar concentration in a solution.
Regularly clean the prism after each use and store the refractometer in a dry, dust-free environment. Check calibration periodically, especially if the device is used frequently or in varying temperature conditions.
The RF30 Refractometer typically comes with a fixed Brix scale. Consult the user manual to check if your model supports additional scales or requires a specific procedure to switch scales.
If the lens fogs up, ensure that the refractometer and sample are at the same temperature. Allow the device to acclimate to the ambient temperature to prevent condensation.
Store the RF30 Refractometer in its protective case in a cool, dry place. Ensure the prism is clean and dry before storage to avoid any residue buildup.
The RF30 Refractometer is best used at room temperature, typically between 20°C and 25°C (68°F and 77°F). Extreme temperatures can affect the accuracy of readings.
If the refractometer is not focusing properly, adjust the eyepiece by rotating it until the scale comes into clear view. Ensure that the refractometer is clean and free from obstructions.
