Aimed at the "first level" of mains analysis, the PQM-1000 is an easy to use, low cost mains monitor, designed to fit into any tool kit or briefcase. Whether used for pre-installation mains investigations or fault finding, it provides accurate information on the quality of any single phase supply.

The main features of the PQM-1000 are as follows:

  • All types of AC mains disturbances monitored.

  • Power Failures (Blackouts)

  • Voltage Drops (Sags)

  • Low Line Voltages (Brownouts)

  • Voltage Surges (Surges)

  • High Line Voltages (Over Voltages)

  • Voltage Spikes L-E & N-E (Impulses)

  • High Frequency Noise L-E & N-E (Impulses)

  • HighlLow Line Frequency

Total of 15 Pre-set thresholds - no programming required.

LED indicators to show occurrence of past or present disturbances.

Two line Liquid Crystal Display (LCD) provides "real-time" display of Line Voltage and Line Frequency, High Frequency Noise (L-E & N-E), and the Disturbance Event Counts.

Simple operation using only 2 keys enables, scroll up or down through the different displays and event counts, and the event count memory to be cleared.

Powered directly from the monitored supply, no special connections are necessary.

Battery backed memory holds data during prolonged power failures.

Dimensions: 196H X 100W X 40D (mm) Weight: 550gms.

Optional Extras: Carrying Case.
