Why The Thermometer?
The density of a liquid is indirectly proportional to its temperature. As the temperature increases the density decreases. Hydrometers are typically calibrated at 60 F. To accurately assess the density of a liquid, a measurement should be taken at the temperature which the hydrometer was calibrated. When that is not possible and the temperature deviates from the 60 F standard, corrections must be applied to the hydrometer reading. This thermometer is scaled with the appropriate temperature correction for the hydrometer reading.
Bellwether Hydrometers are manufactured in strict accordance to specifications of ASTM (American Society for Testing and Materials) for accuracy and design.
