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 Spectrum 8864 Data Controller is a sophisticated, powerful hardware bridge between ESC Spectrum 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 Spectrum, it’s no wonder the 8864 is the most popular data controller available.
