That all makes sense.. So to minimize the effects of evaporation do you suggest to use smaller containers, with more frequent refills? Like maybe get 2x 250ml container?@robbyg
As mentioned earlier, the life span depends on the quality of the water. Just because one tests 1x/week doesn't necessarily mean the sensor will last longer if the water quality is not so great. On the other hand, if the quality is good the sensor will see a lengthier life.
Of course there will be a correlation between number of tests too because if one tests 500 times with "dirtier" water compared to 500 tests with "cleaner" water, the life span of the sensor will not be the same.
Regardless, the diagnostic feature will check the sensor performance and tell you when it's time to consider replacing.
If reference fluids are kept stored at room temperature, un-opened, away from sunlight, you'll easily get 1 year out of them. Since these are a special mix of SW fluids, you don't want to leave these with the caps off otherwise they're susceptible to evaporation...and just like SW, when evaporation occurs it changes the ionic concentration which you don't want happening with these fluids.
