My $120 coolant refractometer was a total game changer for part finish

I was getting inconsistent surface quality until I started checking concentration daily, now my parts look great every time. What's your go-to method for keeping coolant in spec?

Thought it was overkill, but you're totally right.

Ever see someone try to wing it with those test strips? My buddy did that for months, always blaming his tooling. Finally grabbed a refractometer after a chat with someone like mark_hernandez12, who said the same thing about it seeming extra. Night and day difference in his finish quality, just like you said. He still kicks himself for not doing it sooner, all that time wasted on bad parts. Makes you wonder how many shops are out there just guessing.
