I bought this to measure the propylene glycol (low toxicity) antifreeze I use in a 30’s Chevy pickup. It’s extremely well-made, the instructions are clear, it’s easy to use and is reliably accurate. Comes in a nice protective case. I’d previously tried the floating ball type checkers but they don’t work reliably with propylene glycol.
