Sper Scientific Battery Coolant Refractometer 300014 - Measures Freezing Point of Automotive Coolants & Battery Charge - for Ethylene Glycol, Propylene Glycol & Battery Acid - 2 pc

Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever. All Sper Scientific refractometers come complete with: Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat. Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements. All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes and protective cases. 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. Battery charge is measured on a third scale using just a few drops of battery electrolyte solution (battery acid). The specific gravity of the battery acid is displayed together with a reading of RECHARGE, FAIR, or GOOD.
