This document is the instruction manual for the HI 96803 refractometer for glucose measurements, describing the features and characteristics of the product.
The HI 96803 is a rugged, portable, and water-resistant digital refractometer designed to measure glucose concentration in aqueous solutions. It utilizes an optical method to determine the refractive index and automatically converts this to percent by weight concentration with automatic temperature compensation (ATC) between 10°C and 40°C. The device features a dual-level LCD display, a stainless steel sample well, and battery operation with an auto-off function.
| Measurement Range | 0 to 85% / 0 to 80°C (32 to 176°F) |
|---|---|
| Resolution | + 0.1% / +0.1°C (+0.1°F) |
| Accuracy | + 0.2% / +0.3°C (+0.5°F) |
| Temperature Compensation | Automatic between 10 and 40°C (50 - 104°F) |
| Measurement Time | Approximately 1.5 seconds |
| Minimum Sample Volume | 100µL |
| Battery Life | 5000 readings |
| Enclosure Rating | IP 65 |
| Dimensions | 19.2(W) x 10.2(D) x 6.7 (H)cm |
Calibration should be performed daily, before measurements are made, when the battery has been replaced, or between a long series of measurements.
The minimum sample volume required is 100µL to cover the prism totally.
If the temperature exceeds the 10-40°C / 50-104°F range, the ATC tag blinks and automatic temperature compensation is disabled.
The instrument is warranted for two years against defects in workmanship and materials when used for its intended purpose.
