The Apera PH700 (AI501) is a laboratory-grade benchtop pH/mV meter designed for reliable, repeatable measurements in commercial cultivation and water-quality testing environments. The kit includes a 201T-F 3-in-1 combination electrode that measures pH and temperature through a single connection, along with premixed calibration buffers, an electrode holder, and an AC power adapter. The meter provides ±0.01 pH accuracy, automatic three-point calibration, and automatic temperature compensation across 0–100°C. It also measures millivolts, enabling oxidation-reduction potential (ORP) measurements when paired with a compatible ORP electrode, which is sold separately. Its IP54-rated housing protects against dust and water splashes, making it suitable for nutrient-mixing stations, fertigation facilities, and laboratory workbenches.

Key Advantage: The Apera PH700 combines accurate pH measurement, millivolt readings, automatic temperature compensation, and electrode-condition diagnostics in one benchtop instrument. Its guided calibration and 50-set data storage support consistent quality-control procedures, while the standard pH electrode can be replaced with a compatible ORP electrode when oxidation-reduction measurements are required. It is particularly useful as a fixed reference instrument for verifying handheld tester readings and checking nutrient batches before irrigation.
