Analog Water pH Sensor V2 (DFRobot Gravity)

Description

Gravity: Analog pH Sensor / Meter Pro Kit V2 For Arduino is a professional Arduino pH Sensor Meter Kit with an industrial electrode. This ph. sensor module is an upgrade for V1 with improvement is calibration method, more friendly use and better accuracy Attention The bottle cap of the probe contains protective liquid (3.3mol/L KCL). Even if the bottle cap is screwed tightly, some protective liquid may still leak around the bottle cap, forming white crystals. But as long as there is still protective liquid in the bottle cap, it will not affect the life and accuracy of the probe. So please use it with confidence. It is recommended that the white crystals be poured back into the protective liquid in the bottle cap. Features Operating Voltage: 3.3 : 5.5V Output: Analog signal: 0 - 3V PH Measurement range: 0-14 PH PH Resolution: ± 0.1pH (25 ℃) response time:< 1min Working environment: Temperature 0～60℃, humidity: 0-100% Gain Adjustment Potentiometer Power Indicator LED Industry pH Electrode with BNC Connector Examples of some substances PH values DFrobot guide on how to calibrate and use gravity water PH sensor with Arduino.
