I'm looking for a manufacturer that specializes in online water quality monitoring units designed for closed water systems. Specifically, I'm interested in units that come equipped with WiFi or SIM connectivity to facilitate remote access and data monitoring. I have a detailed specification ready to share, which outlines the key features and requirements I need for this project. If you have experience in this area or similar products, I would love to hear more about your offerings and discuss potential collaboration. Looking forward to your response!
