Particle Measurement Consulting
When it comes to particle measurements, we have over 30 years of experience in designing, adapting and customizing instrumentation for process applications. Specifically, we have applied laser-based instrumentation in harsh, real-world environments, e.g. steel mills, coal-fired and pulp and paper power boilers, Pharmaceuticals, etc. In addition, we have competitively proposed and received more than 30 contract research grants (approximately $8M) from the Departments of Energy, Defense, and NIH. These R&D grants have aided us in developing real-time process instrumentation over the past three decades.

             Consulting services include adaptation and customization of instrumentation for specific applications,

                                                         along with installation and operational support.
