Отзыв о Efficiently Test Your Antifreeze And Battery Acid With A 3-In-1 Refractometer от Kirt Phillips
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.
- Used to test coolant protection level, works great
- Some models may be difficult to clean properly
