For a Hanna pH Checker I -- $18 plus shipping(under $25) go to aquaticeco.com. I received mine 4 weeks ago. An inexpensive way to try a digital pH meter.
pH meters are somewhat a bother with calibration & storage solutions. Liquid test by HydroFarm is easy - cheap and fairly accurate - I've tested the color coding with the Hanna ph and found it accurate. |
