This is a complete CEMS(Continuous Emissions Monitoring System) unit for monitoring NOx and Oxygen.  System is very versatile has a wide range of alarm and malfunction alarm features.  Is set up for daily auto calibration, can be done manually as well.  System includes stack probe that is 5 feet long with 2" 300# flange for mounting to flue stack. You could easily shorten probe if that is too long for your application.  250+ feet of heat traced sample tubing. Sample tubing bundle has numerous signal and control wires for probe temperature monitoring and control of the  puff back panel that can keep the probe tip clean in flue gases that have particulate. Several different tubes 1/4" and 3/8" are available for calibration gases and sample flow some tubes with direct heat and some with indirect heat.  Heat trace control panel wired and ready.  Stainless braided lines for connecting the puff back equipment  to the probe.  Cabinet has a side mounted air conditioner to keep electronics cool. In the bottom of the cabinet there are sample chillers to remove the liquid from the sample as well as a container for collecting the sample condensate.  This system is suitable for EPA reporting requirements when calibrated with EPA protocol gas.  Would rather sell as a complete system but would consider selling separate.
