Environmental Innovation

Entrepreneurial Origins

Our founder, Gregg Gustafson, dedicated himself to environmental technology for decades. A holder of several patents, Gregg’s work on the HydroStar pump proved instrumental in monitoring the notorious Hanford site.


Submersible Sensor Technology

Since introducing our P7000 pressure sensor in 1985, we have continually developed new capabilities for submersible sensors. Current INW sensors measure temperature, conductivity, pH, redox as well as pressure.
