Ohaus AquaSearcher™ AB33PH Intermediate Benchtop pH Meter

The Ohaus AquaSearcher™ AB41PH Benchtop pH Meter is designed with reliable measurement and precise performance in mind. 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. Selectable resolution from 0.1 to 0.001. Perform up to a 5-point pH calibration using automatic buffer recognition of 5 predefined buffer groups. Calibration log stores ten most recent calibrations. Compact stirrer can be used to uniformly mix solutions to get fast and repeatable results at no additional cost.

With multi-function touch keypad, you can operate the meter as easy as using a smartphone. All of the important information that you may need is shown on a 6.5” large display in multiple languages. Capture your critical readings with measurement stability indicator and selectable end-points modes – Auto-Stop holds a stable reading, Continuous shows changing readings and Timed logs data at specific intervals.

A 1000-item memory for measurements and calibration trail makes for efficient data documentation. Password management is suitable for GLP documentation. Standard RS232 and USB interface allows for connection to external devices such as a printer or computer for transfer or storage of data.
