TABLE 110.- Temperature corrections to readings of Brix hydrometers (standard at 20° C)

[This table is calculated using the data on thermal expansion of sugar solutions by Plato,' assuming the instrument to be of Jena 16111 glass. The table should be used with caution and only for approximate results when the temperature differs much from the standard temperature or from the temperature of the surrounding air]

This table also may be used with instruments that are standard at 17.5° C, as follows: Find the correction for reducing to 20° C in the usual way, and to this add the correction at 17.5° C with the sign changed; i. e., regarded as positive. For example, if the instrument reads 20.00 percent at 24° C, the correction to 17.5° C is +0.26+0.15 0.41, and the true percentage of sugar is 20.41. If it reads 20.00 percent at 18° C, the correction to 17.5° C is -0.12+0.15+0.03, and the true percentage of sugar is 20.03. If it reads 20.00 at 15° C, the correction is -0.28+0.15-0.13, and the true percentage of sugar is 19.87.
