PCE-DRP 1 is a handheld digital refractometer used to determine the sugar content / coffee p1 / refractive index of coffee and similar liquids in the 0 ... 50 % Brix / 0 ... 25 coffee p1 / 1.3330 ... 1.4200 nD measuring range. This waterproof IP65-rated digital refractometer features automatic temperature compensation (ATC) from +10 ... +40 °C / +50 ... +104 °F, as well as a large, easy-to-read LCD that shows both the measured value and the temperature.
 

Measurement parameters:
- Brix, coffee p1, refractive index, temperature
- Measurement range: 0 ... 50 % Brix 
- Resolution: 0.1 % Brix
- Accuracy: ±0.2 % Brix 
- Automatic temperature compensation (ATC)
