Explore the latest version - Gravity: Analog pH Sensor/Meter Kit V2 to fit your needs. Check our Liquid Sensor Selection Guide to know more about our liquid sensor series. Struggling to measure water quality and other parameters without a low - cost pH meter? Having trouble using it with Arduino? Our DFRobot analog pH meter is the answer! It's specially designed for Arduino controllers, featuring a convenient 'Gravity' connector and a host of useful features. Connect your probe to Arduino instantly and get pH measurements accurate to ± 0.1pH at 25 ℃. With great accuracy and low cost, it's a top - notch tool for hobbyists in biorobotics and other projects. The kit comes with an LED power indicator, a BNC connector, and a PH2.0 sensor interface. Simply connect the pH sensor to the BNC connector and plug the PH2.0 interface into any Arduino controller's analog input port. If pre - programmed, you'll easily get the pH value. It's packed in a compact plastic box with foam for easy mobile storage. Build your own pH meter or water monitoring station for your water tanks. This and our other water sensor devices can create the ultimate water control system. Use it for aquaponics, fish tanks, or any material that needs measurement. Remember, this is a laboratory probe and shouldn't be immersed in liquid for too long. You can check the whole Analog pH Sensor / Meter Pro Kit For Arduino or get a spare Industrial Probe. pH measures the hydrogen ion concentration, with a scale from 1 to 14 (7 is neutral). Acidic solutions have a pH less than 7, and basic ones have a pH greater than 7. Note: Buffer solutions are not included. When you receive the package, you might find white particles on the protection foam, which are KCl crystals from the cap. Don't worry; it's normal due to the transportation restrictions on liquid. Once you get the probe, store it in KCL3N solution; don't leave it dry. Applications include water quality testing and aquaculture. Specification: Module Power is 5.00V, size is 43 x 32mm (1.69x1.26'), measuring range is 0 - 14PH, measuring temperature is 0 - 60 ℃, accuracy is ± 0.1pH at 25 ℃, response time is ≤ 1min, it has a pH Sensor with BNC Connector, a pH2.0 Interface (3 - foot patch), a Gain Adjustment Potentiometer, and a Power Indicator LED.
Using the pH sensor kit is a breeze. First, connect the pH sensor to the BNC connector. Then, plug the PH2.0 interface into the analog input port of your Arduino controller. If it's pre - programmed, you'll quickly get the pH value. There are a few things to keep in mind. This is a laboratory probe, so don't leave it in liquid for too long. Buffer solutions aren't included in the package. When you receive it, you might see some white KCl crystals on the foam; it's normal because of transportation rules. As soon as you get the probe, store it in KCL3N solution. Don't let it sit in dry conditions. For maintenance, make sure to keep the probe clean. Check the connections regularly to ensure accurate readings. And if you're using it in different temperature environments, be aware that the accuracy might vary slightly according to the temperature specifications.
