Instructions & Guidelines - Refractometers
1. Shake the product well before using.
2. Clean the Refractometer prism slide with fresh distilled water.
3. Dry completely with a soft clean dry cloth.
4. Place several drops of Brightwell Refractometer & Hydrometer Calibration Standard fluid on the slide.

Instructions & Guidelines - Hydrometers
1. Shake the product well before using.
2. Rinse the Hydrometer with distilled water.
3. Pour Brightwell Refractometer & Hydrometer Calibration Standard fluid carefully into the hydrometer to avoid bubbles.
4. Tap the hydrometer to dislodge any bubbles and use a stirring rod to tap the swing arm to release any remaining bubbles.
5. Read the hydrometer, at 25 degrees c ( 77 degrees F ) you should read a specific gravity of 1.026
