American Marine PINPOINT pH Probe

Writing this review after 1 year of use. So far is has worked great and is a good value. I have it working with the Atlas Scientific board in my Reef-Pi setup. The much more expensive Atlas probe died after 1 year and was not as accurate. So I would buy this again in future.

Connected easily to my Neptune Apex.

I wont really know until I know how long it lasts. The orginal one did not last long at all.

Compaired to hanna and milwaukee probes and or checkers this ones seems a little off not by much but still off..

I bought this to use with a raspberry pi grove pi from Seeed Studio for a controller I am building. This works great with the Seeed Studio pH sensor kit. It gives accurate readings with it. I cant speak on how long it stays in calibration and to the level it stays calibrated. But so far it works great. The main thing is it will work with the raspberry pi board.

Que es útil práctico y cumple el objetivo

Using to monitor pH in my CO2 injected planted aquarium. Easy to check at a glance that I have optimal CO2 levels that arent approaching dangerous levels for my fish.

Been working great for the last two months on a Reef Angel +. Upon arrival, there was some seepage but it calibrated quickly and has been going strong since. Wouldnt hesitate to order another.

Works perfectly. I hooked it up to the HCS12 MC9S12C128 microcontroller and it produced proportional voltages correctly. Keep in mind that you need to purchase the calibration solutions (#7 and either/and #10, #4) to make sure your sensor is reading properly. The probe will read properly every time; negative voltages for one side of the pH scale and positive for the other. However, your sensor (be it homemade or bought) may not interpret and display the CORRECT pH value without calibration first.

Works great
