ESC | Spectrum provides industry-leading products and services for customers in the electric power and petroleum industries.

Our Data Acquisition System (DAS) is the premier Continuous Emission Monitoring System (CEMS) in the U.S.  The StackVision software and the 8864 Data Controller hardware unite to create the most robust, reliable DAS solution available for air compliance monitoring needs, including CEMS, continuous opacity monitoring systems (COMS) and continuous parametric monitoring systems (CPMS).

RATAView software helps stack testers perform Relative Accuracy Test Audit (RATA) tests accurately and efficiently to meet complex regulations, including requirements around testing frequency, calculations, data gathering and data retention.

Our hardware and software solutions are backed by a wide range of services, from Reporting, Engineering and IT services to CEMS mobile testing, stack testing, equipment repair, calibration, parts and more.

The 8864 Data Controller

The ESC 8864 Data Controller is a sophisticated, powerful hardware bridge between ESC|StackVision software and your emissions monitoring rack. It is, in essence, the engine that will power your emissions data collection and reporting. With more storage capacity, the latest firmware, and plenty of expert support from ESC, it’s no wonder the 8864 is the most popular data controller available.

Wide Range of Communications

The 8864 is an agile, sophisticated tool that can acquire emissions data from analyzers—and operational data from control systems—via digital inputs, analog inputs, and Modbus over Ethernet. It will also output data, flags, and commands through these channels. With plenty of power and speed available, the 8864 can be your one-stop shop for multiple data inputs and outputs.
