Real-World Testing: Putting HB Instrument Company Specific Gravity Hydrometers, ASTM 83H to the Test
First Use Experience
My initial testing ground for the HB Instrument Company Specific Gravity Hydrometers, ASTM 83H was my home brewery. I used it to measure the specific gravity of wort before and after fermentation, a critical step in calculating alcohol content. The hydrometer required a graduated cylinder filled with the liquid to be measured.
The hydrometer performed admirably, providing clear and consistent readings even with slightly turbid wort. The temperature corrections were straightforward, and the results aligned with my expectations based on the recipe. I found the process intuitive, though I exercised extreme caution due to the fragility of the glass.
There were no major issues, although I quickly learned the importance of handling the hydrometer with extreme care. One slight bump against the side of the graduated cylinder made me acutely aware of its delicate nature. However, the precision and clarity of the readings were worth the extra attention.
Extended Use & Reliability
After several months of use, the HB Instrument Company Specific Gravity Hydrometers, ASTM 83H has proven to be a reliable and consistent tool in my brewing process. It continues to provide accurate readings, and the scale markings remain clear and legible. The hydrometer has held up well, despite the occasional minor mishap.
Aside from the ever-present risk of breakage, the hydrometer has shown no signs of wear and tear. I clean it carefully after each use with warm, soapy water and store it in its protective case. This simple maintenance routine seems sufficient to keep it in good working order.
Compared to my previous, less precise methods, the HB Instrument Company hydrometer has significantly improved the consistency and predictability of my brews. The ability to accurately measure specific gravity has allowed me to fine-tune my recipes and achieve more consistent results. It has far surpassed my previous experiences.
