The Flir Extech RF41 Refractometer is a precision instrument designed for accurate measurement of various liquid concentrations. It features a range of 1.3330 to 1.4419 for refractive index measurements, ensuring precise readings for applications in laboratories, food and beverage industries, and more. The RF41 employs an easy-to-read analog scale that facilitates quick interpretation of results, eliminating the need for complex calculations. The device is crafted with a high-quality optical glass prism that ensures durability and resistance to scratches, enhancing long-term reliability.

Constructed with an aluminum body, the RF41 is lightweight yet robust, providing ease of handling and resilience against harsh environments. Its ergonomic design includes a rubber grip for comfortable use, minimizing user fatigue during extended periods of operation. The refractometer requires minimal sample volume, allowing for efficient and economical testing. Calibration is straightforward, supported by an included calibration solution to maintain accuracy.

The RF41 operates in a temperature range of 10°C to 30°C, with automatic temperature compensation (ATC) to ensure consistent measurements amidst varying environmental conditions. This feature is critical for maintaining accuracy, especially in fluctuating temperatures. The refractometer is also equipped with a protective case, ensuring safe storage and transport. The Flir Extech RF41 is an essential tool for professionals seeking reliable and precise refractive index measurements in a compact and user-friendly device.

Flir Extech RF41 Refractometer F.A.Q.

How do I calibrate the Flir Extech RF41 Refractometer?

To calibrate the RF41 Refractometer, place a few drops of distilled water on the prism, close the daylight plate, and look through the eyepiece. Adjust the calibration screw until the boundary line aligns with the zero mark on the scale.

What is the proper way to clean the refractometer?

After each use, clean the prism surface with a soft, damp cloth and mild detergent if necessary. Avoid using abrasive materials or harsh chemicals that may damage the prism.

Why is the reading on my refractometer blurry?

A blurry reading may be due to improper focus. Adjust the eyepiece by rotating it until the scale and boundary line appear sharp. Ensure the prism is clean and free of any residues.

What should I do if the refractometer shows inconsistent readings?

Inconsistent readings can result from temperature variations or a dirty prism. Ensure the refractometer and sample are at the same temperature and clean the prism thoroughly before taking measurements.

How can I measure the Brix value using the RF41 Refractometer?

Place a sample on the prism, close the daylight plate, and look through the eyepiece. The Brix value is indicated where the boundary line intersects the scale.

Can the RF41 Refractometer measure saline solutions?

Yes, the RF41 Refractometer can measure saline solutions. Use the salinity scale to interpret the results. Ensure proper calibration for accurate readings.

How often should I recalibrate my refractometer?

Recalibrate the refractometer regularly, especially if it is used frequently or exposed to varying environmental conditions. Calibration before each use is recommended for critical applications.

What is the temperature compensation range of the RF41 Refractometer?

The RF41 Refractometer includes automatic temperature compensation (ATC) from 10°C to 30°C, ensuring accurate readings across this temperature range.

How do I store the refractometer when not in use?

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

What are the signs that my refractometer needs servicing?

Signs that the refractometer may need servicing include persistent inaccurate readings, mechanical issues with the focus or daylight plate, or visible damage to the prism or housing.
