Hi Donna .You are welcome. This is one tiny info help in return to your great support to our shrimps-lowers community
You will be happy with it. I did some tests. It is very good .5sec response time with water TDS 130 and up. With RO is kind of slow but still work. There are plastic screws on the sensor legs-3mm thick .Firs I decided to take them out in order sensor to react on minimal water leak but when I left it on the tiles under the tanks on the second day he shut down the pumps. He was triggered form condense on the ceramic tiles. Now it is with plastic screw on it and work just fine for a month.
