Overview

Need to measure water quality and other parameters but haven't got any low cost pH meter? Find it difficult to use with Arduino? Our analog pH meter, specially designed for Arduino controllers and has convenient and practical connector and a bunch of features. Instant connection to your probe an your Arduino to get pH measurements at ± 0.1pH (25°C). For most hobbyist this great accuracy range and it's low cost makes this a great tool for biorobotics and other projects! It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. To use it, just connect the pH sensor with 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 compact plastic box with foams for better mobile storage.

Build your own PH meter gadjet, 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.

Features

APPLICATIONS

  • Water quality testing
  • Aquaculture

Contents List :

  • 1x pH probe (BNC connector)
  • 1x pH Sensor Circuit Board
  • 1x Analog Cable
  • Step to Use the pH Meter

    Cautions:

    • Please use an external switching power supply,and the voltage as close as possible to the +5.00V. More accurate the voltage, more higher the accuracy!
    • Before the electrode in continuous use every time,you need to calibrate it by the standard solution,in order to obtain more accurate results.The best environment temperature is about 25 ℃,and the pH value is known and reliable,close to the measured value. If you measure the acidic sample, the pH value of the standard solution should be 4.00.If you measure the alkaline sample, the pH value of the standard solution should be 9.18.Subsection calibration, just in order to get a better accuracy.
    • Before the pH electrode measured different solutions, we need to use water to wash it. We recommend using deionized water.
    • (1)Connect equipments according to the graphic,that is,the pH electrode is connected to the BNC connector on the pH meter board,and then use the connection lines,the pH meter board is connected to the ananlong port 0 of the Arduino controller. When the Arduino controller gets power,you will see the blue LED on board is on. (2)Upload the sample code to the Arduino controller. (3)Put the pH electrode into the standard solution whose pH value is 7.00,or directly shorted the input of the BNC connector.Open the serial monitor of the Arduino IDE,you can see the pH value printed on it,and the error does not exceed 0.3. Record the pH value printed,then compared with 7.00, and the difference should be changed into the "Offset" in the sample code. For example,the pH value printed is 6.88,so the difference is 0.12.You should change the "# define Offset 0.00" into "# define Offset 0.12" in your program. (4)Put the pH electrode into the pH standard solution whose value is 4.00.Then wait about one minute,adjust the gain potential device, let the value stabilise at around 4.00.At this time,the acidic calibration has been completed and you can measure the pH value of an acidic solution. Note:If you want to measure the pH value of other solution,you must wash the pH electrode first! (5) According to the linear characteristics of pH electrode itself, after the above calibration,you can directly measure the pH value of the alkaline solution, but if you want to get better accuracy, you can recalibrate it. Alkaline calibration use the standard solution whose pH value is 9.18.Also adjust the gain potential device, let the value stabilise at around 9.18. After this calibration, you can measure the pH value of the alkaline solution.
