How to choose ph sensor between pro and non-pro
There are two types of pH sensors, and the pro model seems much more expensive. I plan to use it in a fish tank, so under these conditions, approximately how much longer is the lifespan of the pro model?
The difference in pH probe life between the pro and non-pro versions is not significant, with a minimum probe life of 6 months. However, if you are measuring in clear water, the probe life tends to be much longer than that.
And for EC sensors, we don't have a distinction between pro and non-pro. We only have high range and normal range.
DFR0300 (normal range):

10~20000us/cm Low range, Normal concentration , e.g. tap water.
DFR0300-H (high range):

10-100mS/cm High range, High concentration, e.g. seawater.
