The Apera EC700 (AI502) is a benchtop conductivity and total dissolved solids (TDS) meter designed for laboratory testing, nutrient-solution quality control, and commercial cultivation operations. It features a proprietary 2301T-F Brush-Resistant Platinum Black (BPB) combination electrode that measures electrical conductivity and temperature, providing stable readings across a wide EC range of 0–200.00 mS/cm. Automatic temperature compensation helps maintain consistent conductivity measurements as solution temperature changes. The meter supports automatic 1–4-point calibration, recognizes four standard conductivity solutions, and stores up to 50 measurement records. Its configurable EC-to-TDS conversion factor accommodates both 500 and 700 ppm scales, making it suitable for verifying nutrient concentrations, feed water, reservoir solutions, and runoff. The AI502 package includes the meter, electrode, holder, calibration solutions, and power adapter.

Key Advantage: The Apera EC700 combines a wide EC measurement range, configurable TDS conversion, automatic temperature compensation, and stored measurement records in one benchtop instrument. Its wear-resistant platinum-black electrode supports repeatable nutrient-solution testing, while the included calibration standards simplify routine quality-control procedures. It is particularly useful for cultivation facilities that need consistent, documented measurements across feed water, nutrient reservoirs, and runoff samples. Its IP54 rating makes it suitable for a fixed testing bench, but it must be protected from immersion and sustained direct water spray.
