RETK-72 Brix Refractometer Low Sugar, 0~10%

Works Great for Checking Coolant Concentration.

I bought this refractometer to check the concentration of the coolant that I'm using in my camshaft grinder. It is supposed to be between 4 and 5% and this tester makes doing that task very fast, easy and accurate. When the tester arrived I followed the instructions and double checked the calibration using some distilled water and it was right on the money. Ordering was easy and shipping was quick.

EXCELLENT SERVICE
