aichose HPD016 Honey Refractometer

Product Information

The Honey Refractometer is a precision instrument designed for measuring the concentration of honey and other sugar solutions. It features a prism, a cover plate, a calibration screw, a rubber grip, and an eyepiece with focus adjustment. The refractometer comes in three different models: HPD016, HPD017, and HPD018, each with its own specific measuring range and calibration point.

• HPD016: Measuring range of 45-82% Brix
• HPD017: Measuring range of 58-92% Brix
• HPD018: Measuring range of 58-92% Brix, 38-43 Be (Baume), 12-27% Water

The calibration point for all models is set at 78.8% Brix.

Usage Instructions

1. Hold the refractometer in the direction of a light source.
2. Look into the eyepiece and adjust the focus to clearly see the graduations.
3. Open the cover plate and clean the instrument using a soft, damp cloth.
4. Place 2-3 drops of sample water on the main prism.
5. Close the cover plate and press gently to ensure the sample spreads evenly without air bubbles.
6. Hold the device horizontally towards a light source.
7. Look into the eyepiece and read the value where the blue and white intersect the graduated scale.
8. Wipe off and dry the prism after use.

Package List

• 1x Protective carrying case
• 1x Pipette
• 1x ATC refractometer
• 1x Mini-screw driver
• 1x Cleaning cloth

Warnings

1. Accurate measurement requires careful calibration and ensuring that the prism and sample are at the same temperature.
2. Avoid exposing the instrument to damp working conditions and do not immerse it in water. If fogging occurs, seek professional assistance.
3. Do not use the instrument to measure abrasive or corrosive chemicals.
4. Clean the instrument with a soft, damp cloth after each use to avoid inaccurate results and damage to the prism’s coating.
5. Handle and store the refractometer with care to prevent damage to its optical components and structure.

5. With ATC function (ATC Compensation Range: 10°C~30°C (50°F~86°F)).
6. Durable and built to last long.

Calibration Procedure

Note: Honey refractometer calibration needs special calibration with oil and stone. All refractometers are calibrated before being sent out, so usually no need to calibrate them.

1. Firstly, the dioptric oil can attack the cover plate (all plastic and rubber), please keep it away from the cover plate. With repeated contact, the dioptric oil can cause cracking and fogging of the cover plate. When you do the calibration, the calibration stone (reference block) must be used, and it will act as a cover plate.
2. Drop one drop of dioptric oil on the long-sided surface of the calibration stone (reference block). Open the daylight plate, stick the calibration stone (oily side down) on the surface of the prism, and press it lightly with your hand, so that it can not slide down. Rotate and adjust the calibratio nscrew to make the white and blue boundary coincide with the reference reading 78.8% Brix.

You’re done! The unit is now ready to accurately test whatever you need !

Usage Instructions

1. Hold the refractometer in the direction of a light source, look into the eyepiece, and focus the eyepiece to see the graduations clearly.
2. Open the cover plate, and clean the instrument using a soft, damp cloth.
3. Place 2-3 drops of sample water on the main prism, close the cover plate, and press gently so that it spreads across the entire surface of the prism without air bubbles.
4. Hold the device horizontally in the direction of a light source. Look into the eyepiece and read out the value where the blue and white cross the graduated scale.
5. Wipe off and dry the prism.

Package List

• 1x Protective carrying case
• 1x Pipette
• 1x ATC refractometer
• 1x Mini-screw driver
• 1x Cleaning cloth

Warnings

1. Accurate measurement depends on careful calibration. The prism and sample must be at the same temperature for accurate results.
2. Do not expose the instrument to damp working conditions, and do not immerse the instrument in water. If the instrument becomes foggy, water has entered the body. Call a qualified service technician or contact your dealer.
3. Do not measure abrasive or corrosive chemicals with this instrument.
4. Clean the instrument between each measurement using a soft, damp cloth. Failure to clean the prism on a regular basis will lead to inaccurate results and damage to the prism’s coating.
5. This is an optical instrument. It requires careful handling and storage. Failure to do so can result in damage to the optical components and their basic structure.
