Atlas Scientific EZO-pH Embedded pH Circuit .001-14

Works great. I had issues at first but it was due to not fully reading the datasheet. I could not get this ph circuit to function properly with the Raspberry Pi. Half of the time it would display incorrect results or not show at all. The device was being powered incorrectly because I had it plugged into the 5v and not the 3v pin on the raspberry pi. Hope this helps someone who runs into the same issue. After connecting it to the 3v pin, it functions flawlessy.

Works great. Documentation to set it up is online. Easy to follow. Seller through in an extra BNC connector for me. Yay!! Thank you. Took a bit to arrive, but packaging was great. Would buy again. Is there another place in Canada to order these from?

As someone who once sung the praises of Atlas Scientific products, I feel obligated to spread the information that they leave out of their data sheets and documentation. First and foremost, there is NO SUCH THING as a glass bulb pH meter that can be indefinitely submerged and maintain a high degree of accuracy for more than a few hours. It took several hundred dollars, a lot of researching, and hours of trial and error to find out that pH probes are NOT designed to be out of their buffer solution for more than a few minutes. Don't make the same mistakes I did.

Using this interface board is really a no-brainer. Atlas has really made accurate reading of pH probes so simple with this board. I use this board with an Atlas pH probe and it's interfaced to a Raspberry Pi 3 Model B using I2C for communications. I can't say enough good things regarding Atlas or their equipment. Use this pH board and probe if you want accurate, easy, painless pH data in your projects!

The stamp requires moisture free and very clean environment. So, make sure that you put it in a vacuum sealed protective box. I had to buy several of them and they all develop problems with measurements if the stamp is even briefly exposed to anything dirty or corrosive in the air around it.
