The Apera PH9500 (AI5630) is a research-grade benchtop pH and millivolt (mV/ORP) meter designed for laboratories, commercial cultivation facilities, and quality-control operations requiring precise, traceable measurements. It provides ±0.002 pH meter accuracy with selectable resolution down to 0.001 pH. The complete kit includes a Swiss-made LabSen 211 combination pH electrode, an MP500 temperature probe, and Apera's TestBench workstation, which integrates an intelligent magnetic stirrer, flexible electrode holder, and calibration-buffer organizers.
The PH9500 supports automatic 1–5-point calibration, electrode-condition diagnostics, and Good Laboratory Practice (GLP) data management. Its internal data logger stores up to 1,000 measurement records, tagged with electrode ID, user ID, sample ID, company name, date, and time. USB connectivity and the included PC-Link software allow measurements to be exported in CSV or JSON formats for quality-control documentation and laboratory information management workflows. On-screen calibration guidance and calibration password protection help maintain consistent testing procedures across multiple technicians.

Key Advantage: The Apera PH9500 combines high-precision pH measurement with extensive GLP traceability and an integrated laboratory workstation. Its 1,000-record data logger, operator and sample identification, and USB data export make it especially useful for facilities that require documented, repeatable quality-control measurements. The included TestBench simplifies sample stirring, electrode positioning, and calibration-buffer organization, while electrode diagnostics help identify declining probe performance before it compromises measurement reliability.
