Revenue protection

    • Advanced anti-tamper prevention, detection and deterrence
    • Revenue protected against wrong connections such as reversal, interchange of earth/neutral, or partial earthing
    • Extensive forensic information for detection and analysis of tamper attempts
    • Locking arrangement for incoming mains cable, to inhibit wiring tampers
  • Highlights

    • Meter reading in the absence of mains power
    • Integrated base and cover
    • Current and temperature profiled to help detect loose connections and attempts to burn
    • Walkby meter reading over BLE (Optional)
  • Benefits
