Optical Rhino Duo-Chek® Fahrenheit

Automotive Fluid Testers Inquiry About this product

Meets ASTM D3321-12 Standard test method for field test determination for the freezing point of aqueous engine coolants.

Test engine coolant and battery fluid with one instrument

The Rhino Duo-Chek® engine coolant and battery test refractometer offers an accurate, fast and easy-to-use method for testing engine coolant freeze point, glycol concentration, and battery charge condition. Automatic temperature compensation provides immediate, accurate direct readings of ethylene glycol, environmentally safe propylene glycol, and battery electrolyte with only a few sample drops.

Choose between Fahrenheit and Celsius instruments, each Rhino Duo-Chek® measures:

Freeze point of ethylene glycol coolant
% Concentration of ethylene glycol coolant
Freeze point of propylene glycol coolant
% Concentration of propylene glycol coolant
Battery electrolyte specific gravity
Battery electrolyte charge level
