Refractometer Calibration, How to Perform a Single & 2 Point Calibration

This video demonstrates how to perform a Single & Two Point Calibration on a Rudolph J157 Refractometer. The J157 is designed as a high accuracy refractometer for food and water based chemical applications. The instrument can read to ±0.00004 RI / ±0.03 BRIX making it more accurate and reproducible than 4 decimal place wide range chemical refractometers.

Materials used for calibration:
– Distilled Water
– Acetone
– Certified Calibration Fluid
– Paper Towel
