Overview
Dropping into a sample of finished beer, this glass hydrometer floats and gives an analog reading used to judge alcohol by volume and final gravity. It is a Pro Series instrument described as American made and NIST traceable.
Traceability and a plain glass build are the reasons to choose it, since there are no batteries and nothing to calibrate in software. The listing leaves out the scale range and the sample size, so a first-time brewer should check how it will be used.
Who it's for
Home brewers who want to confirm that fermentation is finished and estimate the strength of the batch. Buyers who need a sealed, shatter-resistant meter or a powered display will want a different instrument.
Pros and cons
- NIST traceable for confidence in readings
- Reusable glass body
- Wipes clean after use
- Cleaning cloth included
- Glass can break if dropped
- Measurement range not listed
- Test jar not included
Performance notes
A hydrometer works by floating higher or lower depending on the density of the liquid, and the reading is taken where the surface meets the printed scale. Final gravity and strength readings depend on a clean, steady sample at the temperature the instrument is made for. Wiping the glass between uses avoids residue that would affect the next sample.
