Hanna..screw milwaukee I only use their ph solution. Well for the price of a bluelab I can buy 3 hanna pens n it's the same .1 difference in accuracy. My tap waters 7 so when I'm setting up my shit I turn my pen on n pop it in tap water if she's off I know it's time to calibrate but the hanna is pretty consistent. Hanna also do a more expensive version for like 80e that does the same as the bluelab n comes with a spare bulb n all n still cheaper than the blue lab!
