Ohaus AquaSearcher™ AB23EC Basic Benchtop Conductivity Meter

The next step in the evolution of Ohaus’ original Starter Series, the all-new AquaSearcher™ AB33EC Benchtop Conductivity 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 6½” LCD display and touch keypad makes changing the parameters, executing setup, and performing calibration as simple as using a smartphone.

On-screen text prompts, menu-specific function keys and a multi-language interface shown on a 6.5” large display. Three capacitive touch keys that change based upon use ensures the buttons are never clogged with sample residue. Most of the operation can be done within 3 steps.

Auto-Stop holds a stable reading. Continuous shows changing readings, selectable cell constant allows for use with 2- or 4-cell conductivity cells to measure from ultrapure water to sewage.

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.

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

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.
