The next step in the evolution of OHAUS’ original Starter Series, the all-new AQUASEARCHER™ AB33M1 multi-parameter bench meter is designed with reliable measurement and user-interface in mind. The i-Steward ensures repeatable and consistent measurement accuracy for optimal peace of mind. The 6.5 inch LCD display and touch keypad makes changing the parameters, executing setup, and performing calibration as simple as using a smartphone.
APPLICATIONS: CpH, Oxidation-Reduction Potential (ORP), Conductivity, Total Dissolved Solids (TDS), Salinity and Resistivity with Temperature Measurements
DISPLAY: 6.5" Segment & Dot matrix LCD with backlight
OPERATION: Capacitive touch, ABS top housing, standalone electrode holder
COMMUNICATION: RS232, USB Device (included)
CONSTRUCTION: AC adapter (included)
DESIGN FEATURES: i-Steward, Two Independent Channels, Calibration due alarm, 1,000 measurement memory
- Capable of measuring up to 7 parameters including pH, ORP, conductivity, TDS, salinity, resistivity and temperature, the AB33M1 utilizes 2 independent measuring channels which can work simultaneously.
- With multifunctional touch keypads, AB33M1 makes measurement simple and fast. The intelligent i-Steward monitors the condition of electrodes, ensuring the accuracy of the results.
- A 1000-item memory for measurement and calibration allows for efficient data documentation. Records are kept with date/time for traceability. RS232 and USB enable connection to external devices.
