Apera PH8500-PW Premium Series Portable pH Meter with LabSen 803 Electrode and Data Logger

The Apera PH8500-PW Premium Series is a highly specialized portable pH meter optimized for accurate measurement of purified and low ion concentration water samples—including RO, drinking, distilled, storm, and surface water—making it essential for molecular diagnostics, bioprocessing, and environmental biotechnology workflows.

Key technical features include:

• Swiss LabSen® 803 Glass 3-in-1 pH/Temperature Electrode designed for rapid, stable pH readings and simultaneous temperature measurement in ultra-pure and low ionic strength solutions, critical for biotechnology applications such as gene editing and synthetic biology requiring precise water quality control.
• Data Logging and GLP Compliance: Stores up to 500 data sets with manual and automatic logging options; GLP data management facilitates traceability with calibration date tracking and USB data output for downstream analysis and reporting.
• Intelligent Calibration & Diagnostics: Supports 1-3 point automatic calibration recognizing multiple standard buffers (pH 1.68, 4.00, 7.00, 10.01, 12.45) with self-diagnosis to ensure calibration accuracy, a feature valued in biomanufacturing quality control.
• Robust Construction: IP57 waterproof rating and a protective silicone sleeve for durability in harsh laboratory and field conditions; foldable stand enables use as a benchtop meter, increasing versatility for clinical diagnostics and bioprocess monitoring.
• Enhanced Electrode Technology:
• Proprietary moveable sleeve junction enabling stable readings in low-ion solutions by ensuring free flow of reference electrolyte.
• Blue gel inner electrolyte solution prevents bubble formation and heat convection, enhancing measurement stability and accuracy.
• Swiss-patented pH/temperature combination structure accelerates temperature response by 40%, improving automatic temperature compensation (ATC) for faster stabilization.
• Silver-ion-trap reference system that eliminates silver ion contamination and seals the reference electrolyte against clogging caused by sulfides, proteins, or TRIS buffers, ideal for samples common in molecular biology labs.

This meter is widely adopted in water quality analysis, biomedical engineering, and synthetic biology research, providing reliable, precise pH and temperature measurement with advanced data management necessary for regulatory-compliant biotechnological and environmental applications.
