Profile: Insite Instrumentation Group provides water and wastewater instrumentation to measure, monitor & analyze dissolved oxygen (DO), suspended solids (SS), pH and ORP. Our product line includes dissolved oxygen portable, multi-parameter, DO sensors, suspended solid sensors, and suspended solid multi-parameters. Our InsiteIG model MPA48 multi-channel analyzer is a unique system that combines advanced electronics with solid-state optical sensors. The analyzer will accept any combination of 1 to 8 sensors (DO, SS, pH, and ORP), and automatically configure for the correct operation. The system allows for flexible and economical process monitoring and control. The SS sensor is based on near infrared technology, which eliminates inaccuracies caused by changes in the process color, or changes in particle size. Our InsiteIG model 1500 suspended solids analyzer is a unique system that combines advanced electronics with a solid-state optical sensor. The model 15 sensor utilizes optical principles based on the near infrared (880 nm) range. The model 15 sensor is designed to measure the solids concentrations in biological reactors, open RAS or WAS channels, and clarifier influent channels.
