@Hanna Instruments I keep getting a L.Lo message on my ULR phosphorous reader when I first place the curvette in the checker. I have been sure to wipe the glass carefully, only handle the top, and I have even tried other glass curvettes from the other checker I have. I replaced the battery, just in case. What am I missing?
My dKH reader has worked well for me. No problems there.
