HM COM-80
The first meter I received was dead out of the box. The second one worked good. The problem with this meter is the small screen and not backlit, very difficult to see if working in other than good lighting. I also did not understand what the scales were for until I went on the internet. What I need to understand now is what are good readings for what I am growing. I did a control reading of just plain water I was using and then measured the Bloom liquid fertilizer limited to a 5 gallon bucket, then took more readings with the full 5/5gallon system taken from the reservoir bucket. I hope this is pretty clear. If not, please give me a call. I will be caling Gary again and purchasing a meter with a larger lighted readout. Gene 301-807-****
