Gravity: Analog pH Sensor / Meter Pro Kit For Arduino is a professional Arduino pH Sensor Meter Kit with an industrial electrode. The ph sensor for Arduino has a built-in simple, convenient, practical connection and long life (up to 1 year), which makes it very suitable for long-term online monitoring.

PH is a measure of acidity or alkalinity of a solution. It is commonly used to measure the quality of the water or for water monitoring. The pH scale ranges from 0 to 14.

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.
