Introduction

Need to measure water quality and other parameters but haven't

got any low cost pH meter? Find it difficult to use with Arduino?

Here comes an analog pH meter, specially designed for Arduino

controllers and has built-in simple, convenient and practical

connection and features. 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 BNC 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.

Attention:In order to ensure the accuracy of the pH probe, you need to use the standard solution to

calibrate it regularly.Generally, the period is about half a year. If you meaure the dirty aqueous solution,

you need to increase the frequency of calibration.

pH Electrode Characteristics The output of pH electrode is Millivolts,and the pH value of the relationship is shown as follows (25 ℃): Use the pH Meter Connecting Diagram 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.
