Ohaus AQUASEARCHER™ AB33PH  Standard pH Bench Meter

OHAUS AquaSearcher™ AB33PH 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. 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. 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 multifunctional touch keypads, AB33 makes measurement simple and fast
within 3 steps. The intelligent i-Steward monitors the condition of electrodes,
ensuring accuracy of the results.
• Able to store up to 1000 items in its internal memory, AB33 allows for efficient
data documentation. Standard RS232 and USB interface allows
connection to external devices for expanded storage.
• Auto endpoint mode and auto buffer recognition makes pH calibration
easy. Auto temperature compensation, adjustable TDS factor and two kinds of
cell conductivity probe compatibility are all features well suited for universal
laboratory applications.
• Adjustable TDS Factor - The factor that relates conductivity to total dissolved solids is based on the type of sample being measured. To have correct temperature compensation when measuring conductivity, the linear compensation coefficient adjusts by automatic temperature compensation. Selectable reference temperatures of 20 or 25 ºC for temperature compensated conductivity readings.
