Automatic Temperature Compensation

Temperature is one of the most important factors that affect the accuracy of the brix refractometer reading.

With automatic temperature compensation, you can zero the brix meter with drops of distilled water, but be sure it’s at room temperature within this range: 5℃-45℃.

The greatest thing about ATC is that you don’t have to calibrate the digital refractometer brix manually. You get the same brix readings of a soft drink, be it measured at 10℃ or 25℃.

7 Steps of Measuring the Coffee TDS

① Use the cleaning cloth that comes with the kit to clean the sample tank. Press the blue button to turn on the digital brix refractometer.

② Immerse the glass in the sample tank with distilled water.

③ Short press the button, and then long-press it for zeroing. When the screen displays 0.00%, the calibration is done.

④ Rid the sample tank of any residue.

⑤ Immerse the sample tank with 2-3 drops of coffee fluid.

⑥ Press the blue button to get brix readings, temperature, and the TDS of offee.

⑦ Thoroughly clean the device to make it residue-free.

Note: You may also get a quality rating with the help of DiFluid, an App that connects to the device via Bluetooth and boasts multiple models you can choose before the brix measurement.
