Unlike hydrometers, refractometers have automatic temperature compensation (ATC) so you don’t have to worry about your tank’s water temperature when taking a measurement.
CalibratE YOUR Refractometer. Calibrate the refractometer with a standard solution (typically included with the refractometer) before use. Since the reading will be adversely affected by changes in temperature, it is best to calibrate at room temperature, or within the test environment. If this is not possible, correction charts may be utilized.So, if you are measuring sucrose solutions with your Brix refractometer, you may read percent sucrose directly on the Brix scale. If you are reading non-sucrose solutions on the Brix scale then the readings must be converted into solution concentrations to be useful to the user. . at or near room temperature (20°C / 68°F). Record the .
If you do not have ATC, then you must use a chart (usually included with the refractometer) to get the compensated reading. You simply use the ambient temperature and the reading to obtain a value that must be added or subtracted from the reading to make the compensation. Do not use any temperature corrections when calibrating your refractometer.
By providing precise readings, refractometers enable businesses to maintain the desired quality standards and ensure the optimal performance of their products or processes. . Another factor that can lead to inaccurate readings is inconsistent sample temperature. The refractometer is designed to work best at a specific temperature range .
A refractometer requires calibration if the readings are consistently off when measuring a known standard, such as distilled water (which should read 0° Brix or a refractive index of 1.3330). Regular calibration is recommended to maintain accuracy, especially if the device has been dropped, exposed to extreme temperatures, or used frequently.How Temperature Affects Brix Readings. As mentioned earlier, temperature can impact the accuracy of your Brix refractometer readings. Most refractometers are calibrated for use at a specific temperature (usually 20°C or 68°F). If your wort sample is significantly warmer or cooler than this, your readings may be slightly off.
