DFRobot Gravity: Lab Grade Analog pH Sensor Kit

The DFRobot Gravity Lab Grade Analog pH Sensor Kit is a complete pH measurement kit for Arduino, ESP32 and other microcontrollers. Its laboratory-grade glass probe measures the full 0 to 14 pH range, and calibration buffers are included, so you can start testing water for hydroponics, aquaponics, aquariums or environmental projects right away.

Key features

• 0 to 14 pH with ±0.1 pH accuracy at 25°C
• Laboratory-grade glass probe for liquid analysis
• Upgraded V2 signal board with hardware filtering for steadier readings
• DFRobot library auto-recognizes pH 4.0 and 7.0 buffers for easy calibration
• BNC and Gravity connectors, no soldering
