Auto Express Magazine recently tested the Draper Expert Anti-Freeze, Battery and Screenwash Refractometer Kit, Stock No.10645 and awarded it the ‘Best Buy’ accolade.
“Not cheap, but essential if you want to know exactly what’s in the coolant system. Simply put a couple of drops from the supplied pipette and read the result through the viewfinder. It’s accurate to within a couple of per cent, so this is a top performer. Draper supplies a tough case, plus a screwdriver and distilled water for calibration”.
