I thought the Blue lab truncheon PH pen was the shit,i asked about it at a local hydro shop and they suggested a Milwakee instead. Which is the best piece overall,is there a better choice?
I Love my cheap Milwakee.I buy two at a time as the ones I have are disposables.But I haven't had to throw one away yet.They hold calibration well and for along time.I calibrate once a week just to be sure.
