Our mission is to manufacture innovative and reliable instrumentation that allow our customers to collect measurements in water.

Our History

We are a small family-owned business with over 30 years of experience. Our founder, Dr. Michael J Head, began PME with the development of a small micro-scale conductivity sensor. We now manufacture and design a variety of instrumentation from small loggers to larger monitoring systems. All of our products are specifically created to work in water, for a long time.

PME founded in 1982
