Ohaus Aquasearcher AB41PH Benchtop pH Meter
The Ohaus Aquasearcher AB41PH Benchtop pH Meter is an advanced, research-grade pH measurement instrument designed to deliver accurate, repeatable results with reliable performance and precise measurement capabilities for demanding laboratory applications. Engineered with the intelligent i-Steward system at its core, the AB41PH ensures repeatable and consistent measurement accuracy through real-time electrode condition monitoring, "Electrode Dirty/Broken" alerts, and calibration due reminders that provide optimal peace of mind and help maintain measurement integrity. With selectable resolution from 0.1 to 0.001 pH, this high-resolution bench meter performs up to 5-point pH calibration using automatic buffer recognition across five predefined buffer groups, storing the ten most recent calibrations for comprehensive calibration trail documentation. The AB41PH measures pH, oxidation-reduction potential (ORP), and temperature with three selectable endpoint modes—Auto-Stop (holds stable readings), Continuous (shows changing readings), and Timed (logs data at specific intervals)—enabling flexible measurement strategies for diverse analytical requirements and experimental protocols.
Equipped with a large 6.5-inch segment and dot matrix LCD display with backlight, the AB41PH offers exceptional visibility and information presentation across multiple languages, making parameter changes, setup execution, and calibration procedures as intuitive as using a smartphone. The capacitive touch keypad provides simple and precise control, while the compact integrated stirrer uniformly mixes solutions to achieve fast, repeatable results at no additional cost. Built to support GLP/GMP compliance, the AB41PH features a 1,000-item measurement memory, password management for user access control to specific functions, and activity logs with audit-trail report generation via SPDC software to assist with 21 CFR Part 11 regulatory compliance. Standard RS232 and USB interfaces (included) with GLP/GMP data output capabilities and real-time clock enable seamless connection to external devices such as printers and computers for data transfer, storage, and documentation. Constructed with durable ABS housing, standalone adjustable electrode holder, and operating on AC adapter (included), the AquaSearcher AB41PH meets IEC/EN 61010-1 product safety, IEC/EN 61326-1 Class B electromagnetic compatibility, FCC Part 15 Class A, and Canada ICES-003 Class A standards, making it the ideal solution for research laboratories, pharmaceutical development, analytical chemistry, and quality control environments requiring the highest standards of pH measurement accuracy and regulatory compliance.
