PQA 8000H Rack Mount

Permanent Precision. Built for the Grid.

The Premium Device for Professional Monitoring

With the new PQA 8000H-RM, NEO Messtechnik brings the full measurement capability of the PQA 8000H into a 19″ rackmount form factor — designed for permanent installation in substations, battery energy storage systems, and grid-connected infrastructure. The instrument retains all hardware and software capabilities of its portable variant, while adding a higher-performance processor and up to four integrated IPCS 10A Zeroflux sensors.

Without display or battery, the PQA 8000H-RM is purpose-built for headless, continuous operation and remote access.

IPCS 10A Zeroflux current sensors included — highest accuracy AC/DC current measurement, directly powered by the instrument.

: GPS Time Synchronisation

Highly precise UTC-referenced time stamping — fundamental to PMU synchrophasor measurements and wide-area monitoring applications.

: Up to 1 TB SSD Storage

Continuous raw data recording at full 1 MS/s sampling rate. Local storage combined with remote access via LAN, WLAN, or LTE.

: Remote Access

No on-site presence required for configuration, monitoring, or data retrieval.
