Introduction

You may check the latest version - Gravity: Analog pH Sensor/Meter Kit V2 to meet your requirements and Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.

Need to measure water quality and other parameters but haven't got any low-cost pH meter? Find it difficult to use with Arduino? DFRobot analog pH meter, specially designed for Arduino controllers and has a convenient and practical "Gravity" connector and a bunch of features. Instant connection to your probe your Arduino to get pH measurements at ± 0.1pH (25 ℃). For most hobbyists, this great accuracy range and its low cost make this a great tool for biorobotics and other projects! It has an LED that works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in a compact plastic box with foams for better mobile storage.

Build your own PH meter gadget or a water monitoring station for your water tanks. This and our other water sensor devices could make for the ultimate water control device. Use it for your aquaponics or fish tanks or other materials that need measurements. 

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

Analog pH Sensor / Meter Kit For Arduino Connection


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.

Very good as description

MAREO.JACOBS Nov 16, 2021

Working fine, once calibrated it the readings are very accurate.
