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.
