ph probe has a bubble

[dnastynice]

MY probe is screwed up and doesnt work. worked for about 3 months. it will not calibrate just reads 7 no matter what. was reading 1,3 for a while. there is a bubble in the tip is this probe shot out so soon or is there a trick to fixing it? i have 7.0 and 10.00 to calibrate but doesn't work.

If there is a bubble, you need to get it out of there. Shake it and it should make it rise.
The tip should be filled with liquid and not air.
