Gravity: Analog pH Sensor V2(PRO)

SKU: SEN0169-V2

Gravity: Analog pH Sensor PRO V2 is a high-precision solution for 7/24 continuous pH monitoring in aquaponics, aquaculture, and environmental water testing. Upgraded for accuracy and ease of use, it features an onboard voltage regulator, hardware-filtered low-noise output, and an industrial-grade electrode for long-term stability. The sensor supports quick, solder-free integration with main control boards, and its software library simplifies setup with two-point calibration and automatic buffer solution recognition.
