Product Description
Glycol, Battery, Coolant Refractometer - Sper Scientific (Model 300014): Industrial & Scientific. Battery charge is measured on a third scale using just a few drops of battery electrolyte solution (battery acid). This refractometer measures the freezing point of automotive coolants in their current concentration as well as battery charge. Both ethylene glycol and propylene glycol antifreezes can be measured, on separate scales. The specific gravity of the battery acid is displayed together with a reading of RECHARGE, FAIR, or GOOD.
