Multi-point Extractive Probe

EES Delta Measurement manufactures multi-point continuous combustion analyzers for use in particulate-laden gas streams including utility, industrial boilers and lime / Cement kilns.  EES Delta Measurement's analyzers, measuring CO, O2, NO, and more, assist in improving combustion and reducing NOx, loss-on-ignition (LOI), and slagging. With this new best-in-class O2, CO and NOx instrumentation for feedback and optimization EES Delta Measurement can offer customized engineered solutions for challenging environments.


EES Delta Measurement uses a patented extractive probe head with an automatic purge designed for applications that contain heavy particulate and high ash loading. Various length probes can be installed in a grid formation and local cabinets can be mounted close to extraction probes for simple and low-cost installation.
