Testing runoff with my BlueLabs ppm meter it does not matter if I am testing ppm 500, ppm 700 or EC I am getting a reading of "0r" I have never seen this before. Has anyone else seen this before?
I think he's having issues with an EC monitor ... And which brand did you have a bad experience with? I've had good luck with my Bluelab Monitor thus far. It's both pH and ECI bought an expensive name brand ph pen from a hydro store and the readings jump around and change drastically with a few drops of ph solution. I bought a two pack of etekcity ph pens from amazon for around 20$ and the first one still works great so I have a brand new replacement still in the box. They also come with a nice plastic case, calibration powders and two sets of batteries.
