  • Analog pH meter designed for Arduino controllers
  • LED to work as the Power Indicator, a BNC connector and PH2.0 sensor interface included
  • Measuring Range: 0-14PH
  • Accuracy: ± 0.1pH (25°C)

The Analog pH Meter Kit is 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 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.

Works well

Set the probe up with Arduino, works well. Have not yet tried to calibrate

Adrian Dragos
Ready to use with Arduino

Very easy to use with Arduino: connect and power it. Make the software compensation for the value, it may drift in time (temperature, etc). the only downside is that does not have any PH calibration solutions. For the cost of those (+/- $3), could be included for the first calibration. Either way, it may be calibrated by shorting the BNC input. Used it several times and works very well. A link to the wiki page of this product would be useful to be included here on the page - as for other products.

Good product

This worked perfect for my daughter's project. We are happy

Works well

Ph probe works well as expected.

Very Pleased

Although I have not had a chance to set it up yet, I was pleased to see the 3 Molar KCl solution around the probe was full, and not leaking. Still have to find a source for either Potassium Chloride to make the solution or a premade 3 molar solution.
