Me neither I test two of them. I dont have them any more. They sell for 120 bucks and for the same price I can get a hanna 9044 which has a digital display, ph to the tenth, microsiemens, ppm, and temp. and is a constant monitor which plugs into the wall.
karmaxul Reviewed by karmaxul on . Is there a pH controller? I am looking to find a product i can use to administer ph up or down as required without having to do it myself. Is there such a product? If so how does it work? Rating: 5
