pH Monitor

I was always under the impression pH monitors were crazy expensive, is this one a rip-off or were my thoughts misguided?

Looks ok, my biggest concern would be that it is shipping from Hong Kong.

It looks alright to me too but I have always been leery on those types of things. I saw an ammonia thermometer once and was curious but I am not willing to mess with it lol. Sometimes it is good to step out of the box though! If you get it please update us on its accuracy

My only concern is that sw is never mentioned. I just wonder about corrosion.

Yea, thats a valid point. I remember in chem class we had to keep the ends of ours in this little bottle when stored to keep them clean. I wonder what it was.

Also with mention of Saltwater. The calibration solutions they give you are a little low. Typically with saltwater you calibrate with 7.0 and 10.0 solution. However, the range went to 14 which is plenty high enough. Hard to say.

I bought one of those about a year ago. it lasted me about a month. imo it is junk.

 

[Jimbo7]

did something happen to it or did it just stop working someday?

The probe leaked and got water inside. As far as I could tell there is no way to replace it, a whole new unit is needed.
