American Marine PINPOINT pH Probe

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.

Like the title says. I bought it, plugged it in, calibrated it, put into sump, and have been getting accurate reading since. ** If you dont see it on your APEX controller UI, make sure you have PH probe enabled ** ** Dashboard > Three cog icon > Thermometer icon > PH (make sure checkmark is next to it) **

Doesnt work! Probe arrived in a make shift box, looked used, and was dried out with a piece of paper towel in the probe cover! Save your money and buy somewhere else!

Connected easily to my Neptune Apex.

Good value. Holds its calibration well and stabilises at a new reading fairly quickly. Its not a high priced unit so I did do a quick check on the accuracy. After calibrating with standard buffers at 7.0 and 10.01 I made up a pH 7.8 potassium phosphate buffer solution and the probe (with American Marine pinpoint pH meter) gave a reading 0f 7.79. Im a home user and only interested in the range from 7.0 to 9.0 so please bear that in mind when reading my review.

Piece of garbage will not calibrate. With the 7 solution I can not even turn the dial enough to get it past 6. Waste of money

I have used many probes this one came broken Pinpoint are as a rule a good probe mine was encrusted about 1 above the rubber tip cover had to soak probe to remove rubber cover. Then it did not work well in Cal. solution then after looking it over well I noticed the sensor bulb was broken full refund and got a Neptune and I prefer them and Milwaukee myself But they all can be broken

GREAT PRODUCT, THANK YOU...

The probes dont maintain their accuracy forever and are expected to need to be replaced eventually. The new probe restored accuracy

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.
