Flir Extech RF11 Refractometer F.A.Q.

How do I calibrate the Flir Extech RF11 Refractometer?

To calibrate the RF11 Refractometer, use distilled water at a temperature of 20°C. Place a few drops on the prism, close the daylight plate, and adjust the calibration screw until the boundary line aligns with the zero line.

What is the proper way to clean the prism of the RF11 Refractometer?

Clean the prism with a soft, lint-free cloth moistened with distilled water or a mild detergent. Avoid using abrasive materials or solvents that could damage the prism.

How should I store the RF11 Refractometer when not in use?

Store the refractometer in a cool, dry place. Ensure that the prism is clean and dry before storage, and keep the device in its protective case to prevent damage.

What should I do if the RF11 Refractometer does not give consistent readings?

Ensure the refractometer is properly calibrated, the prism is clean, and the sample size is adequate. If the issue persists, consult the user manual for further troubleshooting steps.

Can the RF11 Refractometer be used to measure the salinity of seawater?

Yes, the RF11 Refractometer is capable of measuring the salinity of seawater. Ensure the device is calibrated correctly for accurate readings.

What is the measurement range of the RF11 Refractometer?

The RF11 Refractometer has a measurement range from 0 to 32% Brix scale, suitable for various applications, including food and beverage testing.

How often should I calibrate the RF11 Refractometer?

It is recommended to calibrate the RF11 Refractometer before each use to ensure accurate measurements, especially when switching between different types of samples.

Is it possible to measure samples that are not liquid with the RF11 Refractometer?

The RF11 Refractometer is designed for liquid samples. For non-liquid samples, they must be dissolved in water or another appropriate solvent before measurement.

What should I do if the RF11 Refractometer's prism becomes scratched?

If the prism is scratched, it may affect measurement accuracy. Contact the manufacturer for repair or replacement options, as attempting to fix it yourself could worsen the damage.

How do I know if the RF11 Refractometer is malfunctioning?

If the refractometer consistently provides inaccurate readings even after calibration, or if the optical clarity is compromised, it may be malfunctioning. Consult the manual or contact technical support for assistance.
