HI 9026 is an advanced pH/ORP meter specifically designed to provide affordable and very precise results under harsh industrial conditions. The meter features a backlit display for clear readings in the darkest environments.

You can choose from 7 memorized buffer values for pH calibration, from very acidic (pH 1.68) to extremely alkaline (pH 12.45). In addition, the user can program 2 custom buffer values, for the best fit to your application.

When calibration is complete, the electrode condition is displayed which indicates that the electrode is working properly and when it needs to be cleaned or replaced.

The user can also set up a calibration time-out from 1 to 14 days and will be alerted when it is time to recalibrate the meter.

HI 9026 is housed in a waterproof casing and can also be used with ORP electrodes. It comes complete with HI 1230B pH electrode and HI 7662 temperature probe and features automatic temperature compensation (ATC) for accuracy and consistency.
