The Apera PH950 (AI5620) is a laboratory-grade benchtop pH meter designed for routine nutrient-solution testing and quality control in commercial cultivation facilities. It provides ±0.01 pH accuracy across a measurement range of 0.00–14.00 pH and includes a Swiss-made LabSen® 211 glass combination pH electrode, an MP500 temperature probe, and the Apera TestBench 606 workstation. The TestBench integrates a flexible electrode holder, an intelligent magnetic stirrer with stepless speed control, and organizers for calibration solutions, creating a dedicated testing station for daily pH measurement and calibration. The meter supports automatic 1–3-point calibration, electrode-condition diagnostics, and automatic temperature compensation. Its onboard data logger stores up to 100 timestamped measurement records, while USB connectivity and the included PCLink-950 software enable data export to a computer for quality-control documentation and operational recordkeeping
