Product Details

The TSI Planar Laser-Induced Fluorescence (PLIF) system provides non-intrusive, global measurements of scalar quantities such as temperature, concentration, pH, and species. Fluorescence measurements are routinely applied in research areas such as combustion, mixing, spray analysis, contaminant mass transfer, and plasma physics. The TSI PLIF system is engineered on a flexible platform built for expansion, and advanced analysis algorithms are incorporated into a user-friendly environment for simple, accurate quantification of the property of interest based on the measured fluorescence intensity field. The PLIF system can be seamlessly coupled with a TSI PIV system for simultaneous global velocity measurements, thus providing information on heat and mass fluxes.

Features and Benefits

  • Provides global measurements of scalar quantities such as concentration, temperature, pH, and species
