ecom-J2KNpro In and Ins
Ultimate combustion analyser


The ecom-J2KNpro industrial represents the ultimate design in accurate gas analysis and is unsurpassed in the field of premier portable emissions analysers. If you have a heavy-duty testing schedule, this is the analyzer for you. In addition to holding up to 6 electrochemical sensors, the ecom-J2KNpro industrial supports an NDIR bench to measure CO2, CO up to 63,000ppm, and CH4.

This allows measurement of 9 gases in one compact portable analyser! When matched with our Advanced DAS Compliance Testing Software, the ecom-J2KNpro industrial offers complete automation of the test procedure so you can get your compliance tests done accurately and efficiently. Advanced features include stack flow velocity, NDIR bench, fresh air bypass switch, heated sensor block for thermal stability, on-board heated line power connection, dual range CO sensors for high accuracy in rich and lean conditions, and the ability to set up automatic test cycling for unattended operation.
