Good luck with that Ph 51. I went through 3 in 4 months They would not calibrate after a couple of weeks or the screws in the top would strip. I hope its just me.
Rubberbubbler Reviewed by Rubberbubbler on . Sharp ph 51 Can anybody give me a website where I can get the operating instructions? Really all I need is to know which way to turn the top screws and what each of them are for specifically. Thanks. Rating: 5
