One BRAND NEW RHA-100ATC (or RHA-200ATC) Portable Refractometer in a blue, foam-lined hard plastic case. This model is designed to measure either Propylene Glycol or Ethylene Glycol Antifreezes and Battery Fluid. Checking these fluids will allow you to measure your radiator and battery’s performance. The refractometer will insure that all is working properly, and not causing problems (like rust, prone to freezing, poor charging, poor cooling, etc.). This unit is designed with Automatic Temperature Compensation ("ATC") which allows for ambient shifts in outdoor temperatures, while still yielding accurate results. ATC works between the temperatures of 10'C to 30'C (50'F to 86'F) This unit is also fantastic for testing aviation grade hydraulic oils (like Skydrol), Glycol-based heat transfer fluids, and fire resistant hydraulic fluids used in die casting or foundry applications.
