HI 9026 is an advanced pH/ORP meter specifically designed to provide affordable
and very precise results under harsh industrial conditions. The meter also features
a backlit display for clear readings in the darkest environments.
You can choose from 7 memorized buffer values (pH 1.68, 4.01, 6.86, 7.01,
9.18, 10.01 and 12.45) for pH calibration. In addition, the user can program
2 custom buffer values, in order to best fit the characteristics of the sample.
For example, if you are going to measure wine and must, you can enter the pH
3.00 buffer value for calibration.
When calibration is complete, the electrode condition is displayed, so the user
can be sure the electrode is working properly or that it needs to be cleaned or
replaced.
The supplied HI 1048B electrode features the innovative CPS

(Clogging

Prevention System), ideal for pH measurements in wine and must.
With proper electrodes, HI 9026 can also measure ORP with a resolution up to
0.1 mV.
