MetriNet from Analytical Technology is a unified system for monitoring water quality at remote sites, and then transmitting the data for web-based storage or directly to a customer site. Derived from Network Metrics, the system enables users to assemble monitoring units that fit their individual site requirement. The data is then stored in a standard CSV file format for easy manipulation with Excel or other programs. Individual M-Node smart sensors take the measurements. These devices are a complete sensor and monitor in one miniaturized package. The sensors are available for a variety of water-quality parameters such as free chlorine, total chlorine, turbidity, pH, conductivity and ORP. Each sensor is inserted in its own flow chamber and individual chambers clip together to form a flow system of the size required. Simple quick-release collars provide easy assembly and disassembly. 800/959-0299; www.analyticaltechnology.com
