The freezing point of the sample can also be measured and displayed. A quick and accurate way to measure the glycol concentration in a HVAC or mechanical system is through a hand-held refractometer. Here are a few do’s and don’ts for the proper use of this instrument. Be sure the instrument is clean and dry before use; Use enough fluid to cover the entire measuring prismviscosity, dilutes rapidly under precipitation conditions, and, if dyed, is orange in color. . ethylene glycol (EG) based fluids, a characteristic that makes the PG fluids more desirable in . • Refractometer freezing point measurements. • Temperature of applied fluid/water mixture. • Inaccuracies in freezing point depressant (FPD .
The HI96832 is a rugged, portable digital refractometer designed for the measurement of percent volume and freezing point of propylene glycol based solutions. The HI96832 has a high accuracy of ±0.2% volume and ±0.5 ℃ freezing point and features simple operation that gives reliable results each and every time. All readings are automatically compensated for temperature . How to Use a Refractometer: Types of Refractometers. Handheld Analog Refractometer With an analog refractometer, the sample is placed on a cover plate and a prism and then held to the light to view the scale inside the meter. Handheld Digital Refractometer Digital refractometers require a drop of the tested solution to be placed in a well. That .
For heat transfer applications, lower viscosity is beneficial. Higher viscosity means higher friction loss – i.e. more energy is required to move a more viscous substance through the system. Applications that require glycol also often include turbulators as well, which help minimize the impact of glycol's viscosity by creating turbulent flow.– This unit reads only Fahrenheit. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. This aids in figuring the concentration of a particular glycol fluid. – The Glycol Refractometer is designed for testing for concentration of glycols.
