This manual provides instructions for using the Propylene Glycol Refractometer
The HI 96832 is a rugged, portable, water-resistant digital refractometer designed to measure the % volume and freezing point of propylene glycol-based solutions. It utilizes automatic temperature compensation (ATC) and features an optical design that eliminates the uncertainty associated with mechanical refractometers.
| Range (% Volume) | 0 to 100 % |
|---|---|
| Resolution (% Volume) | 0.1% |
| Accuracy (% Volume) | ±0.2 % |
| Minimum Sample Volume | 100 µL |
| Enclosure Rating | IP 65 |
| Battery Life | 5000 readings |
Calibration should be performed daily, before measurements are made, when the battery has been replaced, between a long series of measurements, or if environmental changes have occurred since the last calibration.
The instrument requires a minimum of 100 µL to cover the prism totally.
If the temperature exceeds 0-40 °C, the 'ATC' tag blinks and automatic temperature compensation is disabled.
