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.
Note: Probe service life depends on water quality and operating conditions.

Yes. The kit is designed for Arduino and Raspberry Pi and works from a 3.3V to 5.5V supply, which suits many common controller boards.
The industrial pH probe supports a detection range of 0 to 14 pH, covering the full standard pH scale for water quality monitoring applications.
The specified measurement accuracy is ±0.1 pH at 25°C. The upgraded transmitter and hardware-filtered output are intended to provide more stable, low-jitter readings.
Yes. The probe is described as industrial grade and supports 7×24 measurement, making it suitable for continuous monitoring setups.
The signal conversion board uses a BNC connector for the probe and a PH2.0-3P signal connector for the output side. It provides an analog output voltage of 0 to 3.0V and accepts a 3.3V to 5.5V supply.
The probe cable length is 500 cm, which helps when the electronics need to be mounted away from the measurement point. The probe temperature range is 0 to 60°C.
