I am currently using Myron brand pH/tds pens. The tds pens works well and reliably, however I am having long term accuracy problems with my pH pen. Even with cleaning and a 3 point calibration the accuracy and repeatability falter. Can anyone recommend a pH pen that works reliably even with consistent daily use? Something simple with a +/-.01 accuracy would be ideal. Thanks
Nobody checks their pH huh? Well for small scale home use I would recommend their products. I am very happy with them generally. The PT2 just doesn't seem to be able to handle the volume of readings I need to take each day.
