The Apera EC9500 (AI5632) is a research-grade benchtop meter designed for precise, documented conductivity and water-quality measurements in commercial cultivation facilities, fertigation laboratories, and water-treatment operations. It measures electrical conductivity (EC), total dissolved solids (TDS), salinity, resistivity, and temperature using the included 2401T-F glass-body conductivity and temperature electrode. With a conductivity range of 0–200 mS/cm and ±1% full-scale accuracy, it is suitable for monitoring nutrient solutions across different concentrations, from low-strength feeds to heavy flowering-stage nutrient programs.
The kit includes the Apera TestBench, an integrated workstation combining a magnetic stirrer, flexible electrode holder, and buffer-solution organizers. Its large, backlit display shows multiple measurement parameters simultaneously, while three salinity modes accommodate different water profiles. The meter also features Good Laboratory Practice (GLP) data management, storing up to 1,000 timestamped records with electrode, user, sample, and company identification. USB connectivity and included PC-Link software allow measurements to be exported for analysis, charting, and quality-control documentation.

Key Advantage: The Apera EC9500 combines multi-parameter water-quality testing, GLP-compliant data logging, and an integrated magnetic-stirring workstation in one benchtop kit. Its capacity to store 1,000 identified measurement records and export them through USB makes it especially useful for commercial cultivation facilities that need traceable nutrient and water-quality records. The included TestBench also keeps the electrode properly positioned, calibration solutions organized, and samples consistently mixed during measurement, helping standardize testing procedures between operators.
