Hi Guys,

my Ph probe was sitting at 10.6.
when doing the calibration number are
ph7 = 887
ph10 = 887

i assume no change in the numbers is an issue?

can anyone assist?

Yup. That's a problem. How old is it? The standard (cheap) ones only last about a year.

I suggest the neptune lab grade probe. I got over 2 years with that one. I then bought some cheap lab grade one from ebay and it lasted a couple months. Just ordered a new lab grade from neptune again. Good price on amazon prime.
