The Apera EC950 (AI5622) is a Value Series benchtop meter designed for accurate, repeatable measurement of electrical conductivity (EC), total dissolved solids (TDS), salinity, and temperature in commercial cultivation and laboratory environments. It uses the 2401T-F glass-body platinum-black conductivity electrode, which measures EC across a wide range of 0–200 mS/cm with ±1% full-scale accuracy. Automatic temperature compensation helps maintain reliable readings as sample temperatures change.
The kit includes Apera's integrated TestBench workstation, combining a flexible electrode holder, an intelligent magnetic stirrer, and organizers for calibration solutions. This setup streamlines repetitive testing at nutrient-mixing stations, water-treatment checkpoints, and laboratory benches. Automatic calibration, electrode self-diagnostics, and a 200-record manual data logger support consistent measurement and routine quality-control documentation without requiring a computer.

Key Advantage: The Apera EC950 combines a wide conductivity measurement range with an integrated magnetic-stirring workstation, reducing the need for separate stirring and electrode-support equipment. Its automatic calibration, 200-record data logger, and multi-parameter display make it well suited to routine commercial nutrient testing. Compared with the higher-tier EC820, it offers lower measurement precision and fewer data-storage features, but includes the TestBench workstation for a more streamlined benchtop testing workflow.
