Review on π¬ Advanced Apera AI423 Multi Parameter Resistivity Instrument: Efficient Analysis and Measurement Tool by Willie Midkiff
28 pages of recommendations
Simply the worst pH meter I have ever seen. There is nothing simple. You cannot turn it off by just pressing the power button. You have to press two separate buttons to turn it off. The instructions have 28 pages. That should tell you something. Calibration requires that you first select the 7.0 ph standard. If you're not lucky.
- Quick and easy From 1 to 5 points Auto. Calibration with calibration reminder (including premixed standards)
- So far so good
