PM - Rish is truly a network controller for water parameters. It works with a host of modbus interface probes, to send information from its remote location to control central location or persons. It is a small non descripted device, equally acting as a slave device at locations or as master device for a remote inaccessible location. It can be adapted to provide information from modbus interfaced probes on water parameters, including but not limited to UVA, UVT, BOD, COD, TOC, DOC, TSS
