Refractometer Troubleshooting. How to get the most accurate refractometer readings. The most common source of error is trying to take readings with the cover open. A refractometer is a lab device that measures how light is bent when it moves into a sample from the air. It is also used to see how fast light travels. Calibrating your refractometer is a simple yet essential task to obtain accurate measurements consistently. If this is not the case, and you suspect the instrument is malfunctioning or giving an erroneous reading, try zero setting it and take a reading of water to check the zero set. The refractive index measured isn't correct (or at least not consistent with what is expected). These issues can be avoided by either 1) storing the calibration solution and refractometer at the same temperature as the tank ( much preferred) or 2) at least letting. A) repeat the measurement, making. The entire refractometer may be cleaned with a soft, clean cloth or paper towel, dampened with a mild liquid dish soap and water. As a general rule of thumb, you should wait about 10 seconds for every 5 °f difference between refractometer temperature and 68°f, or about 30 seconds for each 10 °c difference between the fluid temperature and 20 °c.
