This combo is specially designed for Arduino compatible controllers. It has an LED which works as the Power Indicator, a BNC connector and PH sensor interface. It is very easy to use. The electrode is made of a pH glass electrode and a reference electrode combined composite electrode, which is pH meter measuring sensor for measuring the concentration of an aqueous solution of H (pH value), it is widely used in various fields to be detected in the pH. The PH electrode has a single cylinder that allows direct connection to the input terminal of a PH meter, controller, or any PH device which has a BNC input terminal. The PH electrode probe is accurate and reliable that can give almost instantaneous readings.

Overview:

• PH range: 0-14 PH
• Operating voltage: 5V DC
• Temperature range: 5-60℃
• Zero-point: 7 ± 0.5PH
• Alkali Error: 0.2PH
• Theoretical Percentage Slope: ≧98.5%
• Internal Resistance: ≦250MΩ
• Response Time: ≦1min

Specifications:

• Operating Voltage is 5V DC.
• The best environment temperature is about 25 degree.
• The pH Probe is connected to the BNC connector on the pH Sensor Module，and then use the connection lines,PH Sensor Module is connected to the analogue port 0 of the controller.
• When the controller gets power, you will see the blue LED on board is on.
• Upload the sample code to the controller.
• Put the PH Probe into the standard solution. Open the serial monitor of the Arduino IDE, you can see the pH value printed on it.
• If you want to measure the pH value of other solution, you must wash the pH electrode first.

Specifications:

• PH Electrode Probe
• PH Value And Temperature Detection Sensor Module
