Antifreeze Refractometer

The handheld refractometers are made with a variety of different scales to measure dissolved solids in solution. The various hand refractometers are categorized according to the type of measurement scale required. All are easily transportable for field use, simple to use, and require only an outside light source to be functional. Models with the ATC designation are Automatic Temperature Compensated over a 40º F temperature range.

Battery/Antifreeze/Cleaning Fluids Refractometers
These models are designed for testing the concentration of battery acids, antifreeze liquids and cleaning fluids. The percentage indicator indicates the point of freezing for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution batteries.

Brake Fluid Refractometers
PLT9021 Brake Fluid Refractometers are precision optical testing instruments for measuring the boiling point and water content of DOT3 and DOT4 brake fluids. In seconds and with only two drops of brake fluid an accurate indication of the boiling point or percentage of water content can be obtained. Brake fluid may be measured from the master cylinder or from each of the wheel cylinders. Many automobile manufacturers recommend regular brake fluids inspections, but until now there was never an easy, inexpensive means for testing it. The Brake Fluid Refractometer represents the most accurate field testing means available for determining the boiling point and water content of brake fluids.
