American Marine PINPOINT pH Probe

This works great with the Digital Aquatics Reef Keeper Elite. All I did was calibrate it using pinpoint 7 and 10 pH fluid and it works perfect.

I used them at 80 c high temperature acidic slurry and they are very durable. After a couple days I still found they can measure accurately by checking the standard solution.

works well with reef pi. calibrated beautifully with 4ph and 7ph solution definitely worth the money and came highly recommended.

I had purchased from a friend the electronic part of the PH Monitor but he had broken the probe. Luckily I found this one from these sellers and it was perfect and brand new at a good price. Better than having to spent a 100 on a new unit.

Always use this replacement probe. They hold up better and stay accurate.

Soy químico y estoy usando este electrodo en un equipo Hanna portátil con el mismo conector universal para mi trabajo en tratamientos de aguas industriales. Se calibro fácil y la respuesta y lectura esta dentro de los parámetros . Buen costo beneficio. Llevo 30 días usándolo . Generalmente un electrodo dura entre 8-12 meses y siempre y cuando se lo cuide.

This replacement probe adds new life to my American Marine PH meter. Calibration with this probe is easy and quick. It is working well for my planted tank.

Best ph probe I’ve ever had.

My 2nd one. First one cracked after a short period of time. I was disappointed as I dont recall doing anything that may have caused it but it was just in the bottom of the sump. I now have a probe holder holding the second one and no issues to date. It did need to be calibrated out of the box when used with my Apex aquarium controller.

This pen looks like it has broke on me already. I dont want to wait 10 min to see if that fixes it. Right now after 2 min in 7.0 solution, Im showing a reading of 11.2!@# I put in 4.0 solution for a cpl min, and Im getting a 1.1 reading...wtf!~@! Complete waist of money this pen was. Stick with bluelabs pen!
