Refractometer

Refractometer

• Determines the freeze point protection for coolants
• More accurate than test strips or float-type hydrometers
• Durable storage case included

Ensures adequate freeze and boil-over protection by accurately testing glycol concentrations of radiator coolant. Maintain effective cooling system performance and eliminate risks of engine damage from electrolysis, cavitation and corrosion. Also measures state of charge and specific gravity for electrolyte in lead-acid batteries.
