What pH meters can do in daily life?
That is a good question so I collect many documents and summarize them into one simple chart as below.
Hope this is also helpful for you. If you need pH meters, you may check some options from AZ Instrument Corp

What kind of PH probes AZ could provide?
1. 86P3: ATC pH probe
2. 86P2: pH probe without ATC function
3. 86P4: pH probe for Low Ion Strength without ATC function
4. 86P6: Full glass pH probe without ATC function
5. 86P7: Sharp tip pH probe without ATC function
6. 86P1: Flat surface pH probe without ATC function
7. 86P11: 6mm glass pH probe without ATC function
For the AZ Combo Water Testing Meters (ex: 86031, 86021, 84051), their pH probe is "863P".

D.O. probe troubleshooting
a) Low on electrolyte
Solution: See page 16 of operation manual to refill the electrolyte and run 100% calibration.
b) Membrane defect
Solution: See membrane change procedure and run 100% calibration.
c) D.O. sensor damage
Solution: Could not be fixed by user
2) E01 on temp. and D.O. reading Reason:
a) The probe is disconnected
Solution: Plug on the probe and make sure a good connect
b) The wire inside the probe connector is broken.
Solution: Could not be fixed by user.
c) The inside wire of the probe is broken
Solution: Could not be fixed by user.
3) E03 on temp . and E04 on D .O. reading Reason:
a) The temp. sensor is damaged.
Solution: Could not be fixed by user.
b) The temp. related wire inside the probe connector is broken.
Solution: Could not be fixed by user.
4) E17 on D.O. Reading Reason:
a)100% saturation calibration error
Solution: see membrane change procedure and run calibration again.
5) E31 on temp. and D.O. Reading Reason:
a)The inside wire of the probe is broken
Solution: Could not be fixed by user.
