A refractometer is one of the fastest ways to estimate the sugar density, dissolved solids, plant health, nutrient uptake efficiency, and overall crop quality of fruits, vegetables, and forage grasses. Higher °Brix readings are generally associated with:

• Better flavor
• Higher nutrient density
• Greater mineral uptake
• Improved shelf life
• Better drought resistance
• Reduced pest pressure
• Healthier soils and plant metabolism

The chart below organizes common crops into four quality zones:

• Poor = Weak nutrition, stressed growth, low flavor
• Fair = Average commercial quality
• Good = Healthy and nutrient-dense
• Excellent = Premium quality, highly mineralized crops

Solar thermal systems are designed to deliver decades of efficient heating performance. Whether the system heats domestic hot water, supports radiant floor heating, warms a swimming pool, or supplements industrial process heat, the success of the installation depends heavily on one often-overlooked factor: the condition and concentration of the heat transfer fluid.

Most closed-loop solar thermal systems rely on a glycol-based heat transfer fluid, commonly propylene glycol, to protect collectors and piping from freezing while efficiently carrying heat from the solar collectors to storage tanks or heat exchangers. While the solar collectors themselves may receive the attention, the fluid circulating through the system is the true lifeblood of the operation.

This is where a refractometer becomes one of the most valuable maintenance tools a solar system owner, contractor, or facility manager can own.

For most people, the words tree syrup immediately bring one thing to mind: maple syrup. But across North America and parts of Europe, artisans, homesteaders, and specialty syrup producers are discovering that many other trees can also produce remarkable syrups with unique flavors, colors, aromas, and culinary uses.

If you sell maple refractometers, this growing niche market represents a major opportunity. Producers making birch syrup, black walnut syrup, sycamore syrup, boxelder syrup, butternut syrup, and even certain hickory-based products all need reliable ways to measure sugar concentration during sap collection and syrup finishing.

The good news is that the same refractometers used for maple syrup production are often highly useful for these alternative syrups as well. While there are some important differences in chemistry and processing, the core principle remains the same: measuring dissolved sugar solids (Brix) to control quality, consistency, and final syrup density.

Evans Waterless Coolant and the Critical Role of Refractometer Testing

Modern engines operate hotter, harder, and under more demanding conditions than ever before. High-performance vehicles, turbocharged engines, diesel trucks, off-road equipment, fleet vehicles, agricultural machinery, and classic cars all place tremendous stress on cooling systems. Traditional water-based antifreeze mixtures have served the automotive world for decades, but they also introduce several limitations that can compromise long-term reliability and thermal performance.

That is why many automotive enthusiasts, fleet operators, racers, and heavy equipment owners are turning to Evans Waterless Coolant as a superior alternative to conventional coolant systems.

Unlike traditional antifreeze mixtures that rely heavily on water, Evans Waterless Coolant is engineered to operate with virtually no water present in the cooling system. This fundamentally changes how the cooling system behaves and dramatically reduces many of the problems associated with conventional coolant.

Natural gas processing plants rely on a wide range of technologies to ensure pipeline-quality gas reaches end users safely and efficiently. One of the most critical steps in natural gas treatment is the removal of water vapor from the gas stream. Even trace amounts of moisture can create serious operational, safety, and economic problems throughout the production, transmission, and refining process.

To solve this challenge, natural gas plants commonly use glycol dehydration systems featuring triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (EG), and tetraethylene glycol. These glycol-based dehydration systems are essential because glycols act as highly effective desiccants, absorbing water from natural gas before the gas enters pipelines, compressors, cryogenic systems, or downstream processing equipment.

However, glycol dehydration systems only perform effectively when the glycol concentration is carefully maintained and monitored. Overly diluted glycol loses its ability to remove water efficiently, while contaminated or improperly concentrated glycol can damage equipment, increase operating costs, and create dangerous process conditions.

This is where accurate glycol measurement becomes indispensable.
