American Marine PINPOINT pH Probe

Soaking solution had dried out when I received it. Packaged very poorly.

Needed a new probe. Got a new probe. Its a perfect probe. Long cable is a plus - blue is a plus - plants are happy and the aquarist is happy.

WARNING: Does NOT come with calibration fluid or instructions. It would be nice if they stated this in the description, as the item is useless without calibration fluid. It also does NOT come with instructions.

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.

I have the monitor and the guardian monitor, both needed new probes, these were super cost effective, came packaged safely, plug n play, calibrated in a snap, and has held calibration as well as the OEM part did. (maybe better, as it was replaced, am i right?)

Arrived fast and was as described

Works perfectly with my meter.

best ph probes to use for my apex controller. Cant tell much difference between this and the professional grade. I would save a few bucks.

I bought this in February of this year. It will not take an accurate reading. Ive calibrated it on numerous occasions but it repeatedly reads low. Not worth the money.

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.
