沙特阿拉伯采购需求：单体水质传感器,水质传感器

Could you please provide a detailed catalog for your ph&ec smart meters? I'm particularly interested in the specifications, features, and potential applications of the different models available. Additionally, it would be great to have information on pricing, bulk order options, and any available warranties or support services. This info will help us make an informed decision regarding our procurement needs.
