ENDA-7000 Series

Stack Gas Analyzer

After decades of experience in precise stack gas measurement, HORIBA's brand new ENDA series represents the ultimate stack gas analyzer. With enhanced lower cost and reduced maintenance time, high sensitivity, and usability, we focused on the users' point of view. The ENDA-7000 is designed to continuously measure the concentrations of NO_X, SO₂, CO, CO₂, O₂, and NH₃in stack flue gas streams. The model is offered in dozens of combinations based on your measurement requirements. The ENDA-7000 uses an extractive method which measures undiluted sample gases, and is very suitable to stack gas measurements such as shale gas, LNG, or biogas and other combustion applications. The ENDA-7000 is an excellent choice for measurements in power generation facilities, boilers, furnaces, steel manufacturing, cement plants, pulp and paper mills, etc.

Each system consists of a 15 inch color touch screen display, an analyzer bench which measures up to 6 gas components in a 19" rack mount unit, and a sampling system which includes low maintenance and cost effective vacuum type sampling. The system is also flexibly expandable with other peripheral devices such as dust and flow monitors.

The ENDA-7000 is also capable of remote maintenance linked with other communication devices such as smart phones; therefore you can easily access your ENDA-7000 to monitor the status of sensors and meters wherever you are. The new ENDA guarantees your satisfaction of gas measurement needs.
