Who's Minding the Planet?

About YSI

We work with professionals to develop water monitoring solutions for our planet’s natural resources. Whether you are concerned with climate change, floods, droughts, storm water runoff, clean drinking water, or healthy ecosystems, YSI can partner with you to provide reliable water resource instruments and systems.

Our instruments, software, and data collection platforms are focused on environmental monitoring and testing. The integrated systems we deliver to our customers help them to obtain critical data about the quality of water.

From the GM

At YSI we are interested in partnering with our customers to deal with the impacts of global climate change. What we provide helps you make critical decisions — for wetlands restoration, near-coastal monitoring, water resource planning, aquaculture, and many applications in between.  We are dedicated to responsibly providing the reliable water resource instruments and environmental monitoring systems and data that you need to do this.

YSI also offers Life Sciences products including biochemical analyzers for bioprocess monitoring, food and beverage processing, and sports physiology. This line began with the YSI blood-gas analyzer in the 1950s and is presently the industry “gold standard” for glucose and lactate measurement.

Along with our products, we build relationships with our customers through our dedicated customer service, including technical applications and service support. Our employees have years of knowledge and know-how to share. You can find our trained employees in many locations around the world, ready to assist you quickly.

I welcome your feedback about our products, services, or any other aspect of YSI.
