PCE-DRA 1 is an antifreeze digital antifreeze refractometer used to determine the percentage or content and freezing point of propylene glycol- and ethylene glycol-based solutions. 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: - Ethylene glycol %, propylene glycol %, temperature C - Measuring range: 0 ... 60 % ethylene glycol - Resolution: 0.1 % / 0.1 - Accuracy: 0.5 % / 0.5 C - Automatic temperature compensation (ATC) - Easy calibration with distilled water
