Review on 🌊 HM Digital COM 80 Electrical Conductivity: Boost Water Safety with Advanced Monitoring Technology by John Hall

Does more than I need and what I need does it well. (I use it in EC mode to fertilize a PPS Pro aquarium.) Looks good. Not too big to have handy. Many settings would allow me to communicate with other people using TDS or other modes. My only caveat is that it takes some time (two or three minutes?) to set the final reading (they fluctuate quite a bit when adjusting the temperature). So I hold the meter in the water with one hand and my morning tea with the other, watching the fish happily check the meter. With the exception of an expensive large (sensitive?) instrument, this seems ideal.
