About PME

Who We Are

PME was founded in research institutions 30 years ago and we continue to partner with them today, developing new technologies in R&D settings to support public and commercial research organizations.

Our mission is to provide research institutions with affordable instruments and software that accurately and reliably measure, collect and analyze water properties for both fresh and saltwater research.

We believe innovation begins with the real needs of our research partners.


PME founded in 1982

Core Values

We are fueled by a determination for excellence in our products and service, and a curiosity about new technology, science, and the world around us. We find passion and fun in our work, and hope to see it reflected in our openness as we strive for business and professional growth. Most importantly, we aim to treat our customers, employees and associates with respect and humility.

Our Approach

PME is 100% focused on the satisfaction of our research audience.

All of our products begin with the challenge to find an accurate measuring solution to a unique research problem. We implement bespoke technology for research institutions who come to us with very specific needs. If we determine those needs have broader appeal, we engineer products for use in other research and commercial applications.

When we bring a product to market, we must be convinced it’s the best in a category. It must be tested against all competitors in the field with discerning scientists. Only after it receives our research partners’ seal of approval does it become available for our customers.

Quality is determined by exemplary performance over time. Our products last. They are durable. PME’s innovation extends to creating instruments that must perform in the most difficult environments water can throw at us – freezing temperatures, mud, algae. It also provides researchers with the easiest way to download and analyze the data they need, in a way that is reliable, convenient and useable.

PME Leadership Team

With a deep level of knowledge and experience, our team focuses on innovating technologies and products to address the world’s greatest water challenges that research organizations and aquatic industries face.


Kristin Elliott

President & CEO

Kristin began working for PME in 2006, and became CEO of her parent’s business in 2014. Since taking the reins, Kristin has overseen a period of growth and expansion within PME, tripling the company’s annual revenue. In addition, she founded a new company, Aquasend, and is involved with various business organizations, including the San Diego Entrepreneurs Association. She has an MBA degree from Cal State University, San Marcos.


Dr. Michael and Sandy Head


Mike and Sandy founded Precision Measurement Engineering out of their garage in 1982, as Mike was completing his Ph.D at Scripps Institution of Oceanography in San Diego. The innovative micro-scale sensor he developed allowed researchers to track very small fluctuations of temperature and conductivity in water samples. Mike has long worked on research and development for PME, while Sandy ran operations and ensured production quality. Their daughter, Kristin Elliott, is now President and CEO of the company.


Erik Elliott

Chief Operations Officer

Erik began working for Precision Measurement Engineering in 2007, and he became COO in 2015. Responsible for managing all manufacturing employees and production control, Erik has implemented a variety of manufacturing and quality assurance processes, which have supported PME’s fluid and steady growth trajectory. He ensures the company’s fiscal fitness, so PME may continue to pursue high growth levels.
