was reached. A calibration solution can help referee. OTHER REFRACTOMETER USES As mentioned before, specially calibrated hand refractometers are available to test other than 0-32 brix. For instance Freezing point of anti-freeze mixtures... Saline concentration... Urinalysis Detecting illegal wrestler dehydration... Blood protein testing... Drug tampering... Jelly & jam production... Honey quality... Aquarium setup... Jet fuel quality and contamination... Aquaculture... With practice, a standard brix refractometer can be used to accurately test or help duplicate many aqueous solutions. Example: some farmers buy barrels of 35% hydrogen peroxide to spray on their crops to raise brix levels. 35% H 2 0 2 , itself tests about 17 brix when fresh. However H 2 0 2 gradually breaks down to water in storage. A farmer can check with a refractometer and determine if he is getting what he is paying for. Example: drug store 3% hydrogen peroxide tests 1.5 brix when fresh. It is an easy matter to dilute 35% concentrate down to 3% by adding distilled water to reach an identical reading. Example: Sorbet (frozen fruit mixtures) can be adjusted to obtain more consistent results. FAMILIES OF FRUITS & VEGETABLES BRIX=QUALITY charts are not 100% complete nor finished. New researchers will establish values for unlisted produce. New farmers will re-discover long lost methods to grow higher quality produce. New agronomists will debate among themselves over the merit of a single degree brix. In the interim, the home tester using a brix chart must sometimes substitute the value of a closely related item
