New checker from Hanna!

Might as well use this thread to practice using giphs.

I wonder how much value there is in a pH checker you have to buy reagent for frequently when you could put a bit more $$ up front and only buy calibration fluid to keep it working from there on out.
 
This one?



pH Accuracy (@25°C/77°F) ±0.2 pH

Seriously? So a reading of pH 8.1 could really be pH 7.9 or 8.3?
