Digital Refractometer for Ethylene Glycol Analysis
HI96831
Description
The HI96831 is a rugged, portable digital refractometer designed for the measurement of percent volume and freezing point of ethylene glycol based solutions. The HI96831 has a high accuracy of ±0.2% volume and ±0.5 °C freezing point and features simple operation that gives reliable results each and every time. All readings are automatically compensated for temperature variations and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.
• Fast 1.5 second response time for temperature compensated readings
• Sample size as small as 2 metric drops (100 μl)
• Sealed stainless steel well with high-grade optical prism made of flint glass
Ethylene glycol is used in glycol cooling systems for industrial applications. Maintaining the appropriate percent of glycol is important in glycol chillers as too low of a percentage could lead to the system freezing and rupturing while too much glycol will reduce the systems efficiency. The instrument converts the refractive index of a sample to percent volume or freezing point. These conversions are based on internationally recognized references for unit conversion and temperature compensation for glycol solutions (e.g. CRC Handbook of Chemistry and Physics, 87th Edition). The HI96831 is an easy-to-use tool for measuring freezing point and percent volume in ethylene glycol solutions, in the field or in the lab.
