Power Meters

High-Accuracy Power Meters for Electrical Testing

At Electrotest, we provide high-quality power meters for electricians, engineers, and maintenance professionals across New Zealand. Power meters in NZ are essential tools for monitoring real-time electrical performance, helping you measure voltage, current, and power factor with precision. 

Unlike standard energy meters, which only track total energy consumption over time, power meters give immediate insights into your electrical system, enabling energy management, load monitoring, and preventive maintenance. Whether you need a portable power meter in NZ for fieldwork or a panel-mounted model for continuous monitoring, our comprehensive range of instruments ensures you can maintain safety, efficiency, and compliance in every application.

What is a Power Meter?

A power meter is a device used to measure the electrical power consumed by a circuit or device in real time. By providing accurate readings of voltage, current, and power factor, power meters allow professionals to analyse system performance and identify inefficiencies.

In industrial and commercial settings across New Zealand, power meters are used for:

  • Energy Management: Identify opportunities to reduce electricity consumption and costs.
  • Power Quality Analysis: Detect harmonics, voltage sags, swells, and other issues affecting equipment performance.
  • Load Monitoring: Ensure circuits are not overloaded and energy is distributed efficiently.
  • Preventive Maintenance: Spot potential failures before they cause downtime.

Electrotest offers portable meters for spot checks and troubleshooting, as well as panel-mounted meters for continuous monitoring. Our power meters are reliable, accurate, and designed to meet the demands of any electrical application.

How to Choose a Power Meter

Selecting the right power meter requires careful consideration of several factors:

Single-Phase vs. Three-Phase

Determine whether your application requires single-phase or three-phase measurement. Most industrial and commercial systems use three-phase meters, while smaller setups may only need single-phase.

Accuracy Class

The accuracy class indicates how close readings are to the true value. General monitoring usually requires Class 1, while billing or critical applications may need Class 0.5 or 0.2.

Measurement Parameters

Beyond basic voltage and current, some meters measure power factor, harmonics, and voltage flicker. Choose a meter that tracks the parameters most relevant to your application.

Communication Protocols

If integration with a BMS or SCADA system is required, select a meter that supports Modbus, BACnet, or Ethernet.

Portable vs. Panel-Mounted

  • Portable meters are handheld, lightweight, and ideal for field testing or troubleshooting.
  • Panel-mounted meters are permanently installed for continuous monitoring, ideal for energy management and power quality applications.

Budget Considerations

Prices range from a few hundred to several thousand dollars. At Electrotest, we offer options to suit every budget, including flexible financing solutions.
