Flir Extech RF40 Refractometer F.A.Q.

How do I calibrate the Flir Extech RF40 Refractometer?

To calibrate the RF40 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 line on the scale.

What is the proper method for cleaning the prism of the RF40 Refractometer?

Use a soft, lint-free cloth dampened with distilled water or a mild cleaning solution to gently wipe the prism after each use. Avoid using abrasive materials.

How do I troubleshoot inaccurate readings on my RF40 Refractometer?

Ensure the prism is clean, recalibrate the device with distilled water, and confirm that the sample is at the correct temperature for measurement.

What should I do if the RF40 Refractometer is not displaying a clear boundary line?

Check for dirt or scratches on the prism, clean it if necessary, and ensure the sample is evenly distributed on the prism surface.

Can I measure hot liquids with the RF40 Refractometer?

No, avoid measuring hot liquids as they can damage the prism. Allow the sample to cool to room temperature before measurement.

How often should I calibrate my RF40 Refractometer?

Calibrate the refractometer daily before use or whenever there is a significant change in ambient temperature.

What is the recommended storage method for the RF40 Refractometer?

Store the refractometer in a dry, cool place, ideally in its protective case, to prevent dust and moisture accumulation.

Can the RF40 Refractometer be used outdoors?

Yes, but ensure it is protected from direct sunlight and extreme weather conditions as these can affect measurement accuracy.

What types of solutions can the RF40 Refractometer measure?

The RF40 is suitable for measuring the concentration or purity of aqueous solutions like sugar solutions, saltwater, and other transparent fluids.

How can I ensure consistent results with my RF40 Refractometer?

Ensure the refractometer is properly calibrated, the prism is clean, the sample is at a consistent temperature, and avoid air bubbles in the sample.
