The Evans Analog Refractometer allows you to test for residual water content in your cooling system when doing your conversion to Evans Waterless Coolant. After you have run prep fluid through your vehicle, refilled with Evans Waterless Coolant, and circulated Evans through your cooling system, we recommend using this refractometer to ensure your the water content in your cooling system is less than 3% water (54.4 Brix).
Using the Evans Analog Refractometer is simple - just take a fluid sample from your cooling system and follow the included instructions - no batteries required, this device is completely analog.
