Review on Efficiently Test Your Antifreeze And Battery Acid With A 3-In-1 Refractometer by Kirt Phillips

Revainrating 5 out of 5

Fast and simple freeze point measurement.

Only one drip of coolant required for measurement. Dropper is supplied with the Refractometer. I checked calibration by mixing four solutions; 100%, 60%, 40% and 0%, RO Water/Polyethylene Glycol. Measurements with the Reflectometer were spot on. I recommend this product.

Pros
  • Used to test coolant protection level, works great
Cons
  • Some models may be difficult to clean properly
