395 TPI Handheld Refractometer Propylene Glycol Ethylene Glycol Battery fluid 395 TPI Handheld Refractometer Propylene Glycol Ethylene Glycol Battery fluid

TPI 395 Handheld Refractometer - Use the 395 to determine the freezing point of fluids including those used in hydronic heating systems. The 395 Handheld Refractometer is designed to give an accurate reading regarding the freezing point of fluids used in hydronic heating systems. It is quick and easy to use. Place a drop of fluid on the prism, close the plastic lid, and look through the eye piece: where the blue and white colors meet indicates the freezing point of the coolants or the state of change for batteries.

If the specific gravity measures between 1.100 and 1.220, the battery must be recharged. If the specific gravity is below 1.225 or a variation of .20 or greater specific gravity between battery cells indicates a need for battery equalization charging or indicates a weak cell. If the specific gravity is between 1.225 and 1.265, the battery is ok to test. If the hydrometer has a temperature correction chart, be sure to adjust the reading for the battery’s temperature. Variance of specific gravity between cells is not significant on discharged batteries (batteries with specific gravities below 1.225). However, if there is a variance of 50 points (0.050) in a battery whose specific gravity is 1225 or more, that battery is defective.
