Serge I believe accuracy is the designation for "lab grade" meaning +/- 0.01 or .001 or finer readings.
The "cheapo grade" meanwhile have less resolution like +/- 0.05 or 0.1 ph accuracy.
Both types of glass probes have a manufacturer recommended replacement of 12 months.
I'm going for the "cheapo grade" probes for monitoring - I don't think I need that tight of readings.
I'm switching over to a calcium reactor so I may need the finer resolution probe for adjustments....but I don't anticipate it.
