The meter numbers "may" not be in line and you may be better than you think but could also be worse. Did the meter come with a calibration solution. If so what does it say on the bottle ? And did you calibrate it ? If not we need to fix that.
So far those numbers look like your DI unit is going as it should be 0 ppm. But the meter offset could be that much. _________ Boomer Want to Talk Chemistry ! The Reef Chemistry Forum
