The Ohaus AB33PH-B (30589826) AquaSearcher pH Benchtop Meter is designed to be reliable, efficient, and user-friendly. The i-Steward ensures repeatable and consistent measurement accuracy for optimal peace of mind. The large LCD display and touch keypad makes changing the parameters, executing setup, and performing calibration as simple as using a smartphone.

i-Steward indicators include the pH electrode condition, "Electrode Dirty/Broken," and reminder when meter needs recalibration. On-screen text prompts, menu-specific function keys and a multi-language interface are shown on a 6.5" large display.

Three capacitive touch keys that change based upon use ensure the buttons are never clogged with sample residue. Most of the operation can be done within 3 steps.

Auto-Stop holds a stable reading, while Continuous shows changing readings. Users can perform up to a 3-point pH calibration using automatic buffer recognition of 3 predefined buffer groups.

A 1000-item memory for measurements and calibration trail makes for efficient data documentation. Records are associated with date and time for good traceability.

The standard RS232 and USB interface allows for connection to external devices such as a printer or computer for transfer and storage of data.

A standalone adjustable electrode holder provides full flexibility for different types of electrodes (electrodes sold separately).
