Gravity 7/24 Industrial Analog pH Meter Kit for Arduino & Pi

Overview

Gravity: 7/24 Industrial Analog pH Meter Kit is built for reliable, long-duration pH monitoring in water quality applications. It combines an upgraded analog transmitter board with an industrial-grade pH probe for stable measurements and straightforward integration with Arduino, Raspberry Pi, and other controller platforms.

The kit supports a wide 3.3~5.5V supply range and provides a 0~3.0V analog output, making it easy to interface with embedded systems. Hardware signal filtering helps reduce jitter for smoother readings, while the Gravity-style connection system and BNC probe interface keep installation simple and solder-free.

For practical deployment, the included software library supports two-point calibration and can automatically identify standard buffer solution values. The industrial probe is designed for 7/24 continuous measurement, with a stated accuracy of ±0.1 pH at 25℃ and a long 5m cable for flexible placement.
