I have been using pH meter 999 for 4 months...

I only initially calibrated it and it worked very well for 4 months.
Suddenly one day, I come back home, the pH=7.3 ! But found to be pH meter problem.

I calibrated it again, but it never worked normally afterwards (report pH = 0.3 - 9.6 !).

Do I need to buy a new one? Can I clean the probe? How? (because we cannot touch the probe).

pls help
