Gravity: Lab Grade Analog pH Sensor Kit for Arduino

This is a laboratory probe, it can't be immersed in the liquid for too long time. You can check here for the whole Analog pH Sensor / Meter Pro Kit For Arduino or a spare Industrial Probe as a replacement

What is pH?  

“pH stands for the power of hydrogen, which is a measurement of the hydrogen ion concentration in the body. The total pH scale ranges from 1 to 14, with 7 considered to be neutral. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline.” 

Note: Buffer solutions are not included.

Gravity: Analog pH Sensor / Meter Pro Kit for Arduino and Gravity: Analog Industrial pH Sensor / Meter Pro Kit V2 are intended for testing in aboratory environments only, and the probes are subject to data drift after extended measurements. If you need to measure a solution for an extended period oftime, we recommend using the Gravity: Analog pH Sensor / Meter Pro Kit for Arduino or Gravity: Analog Industrial pH Sensor / Meter Pro Kit V2.

After you received your package! You may found some white particles on the protection foam which is the KCl crystallization from the cap. Please don't worry about the crystallization in the packing box, that's normal. Actually, since the transportation restriction on liquid, we have poured out the KCL3N solution in the cap, the slight crystallization in the packing box should be leaked since the remnant. Anyway, once you received the probe, you should store it in KCL3N solution, you can not leave it in dry circumstances.
