The Apera PC820 (AI533) is a high-precision, laboratory-grade benchtop multiparameter meter designed for commercial cultivation facilities, fertigation laboratories, and water-quality testing. It measures six parameters: pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, resistivity, and temperature. The complete kit includes a Swiss-made LabSen 211 pH electrode and a 2401T-F Brush-Resistant Platinum Black (BPB) conductivity electrode, enabling comprehensive water and nutrient-solution analysis with one instrument. It delivers exceptional pH accuracy of ±0.002 pH and conductivity accuracy of ±0.5% full scale, supporting precise nutrient preparation and water-treatment verification. Its Good Laboratory Practice (GLP) data-management system stores up to 1,000 timestamped measurement records, while USB connectivity and the included PC-Link software enable data export, charting, and quality-control documentation.

Key Advantage: The Apera PC820 combines high-precision pH and conductivity measurement with six-parameter monitoring and storage for 1,000 timestamped GLP records. Compared with the PC800, it improves pH accuracy from ±0.01 to ±0.002 pH and doubles data storage from 500 to 1,000 records. Its USB-based reporting, automatic data logging, and included calibration solutions make it particularly valuable for commercial cultivation facilities that need accurate nutrient-batch verification and traceable quality-control records.
