We've created this quick selection guide to help you narrow down your choices. With just a few clicks you'll be able to pinpoint the right instrument for your application. Once you do that and after you answer a few specific questions, we can get moving on getting the right instrument into your hands.

Portable Instrument or Permanent Installation?

For most applications, a portable instrument will be the correct choice. Nearly all the instruments we offer for sale fit into this category.

If, on the other hand, you are looking for a permanent solution to continously monitor power at the service entrance or on selected branch circuits, then the selection guide will direct you to our recommended solution - the PQube 3.


Portable Device

  • If you are interested in conducting a load study or energy survey, then to choose from our selection under the Logging tab.
  • If you are trying to get to the bottom of power quality problem, then you will want to select the Power Analysis tab

Permanent Installed Device


PQube-3-Hands-e1509477073855.pngPQube 3 Power Analyzer

This compact instrument is simply the best power monitor and real-time sensor you can buy. 

It records every type of AC power disturbance – including 4 MHz sampling of impulses – and it is an IEC 61000-4-30, edition 3 Class A certified, ultra-precise revenue-grade energy meter. Monitor up to two three-phase loads, or eight single-phase loads with a single instrument.

It goes beyond AC power too. Records environmental data – such as temperature, humidity and barometric pressure, vibration, 3-axis acceleration – as well as process parameters, including torque, RPM, fuel level, water flow, and more. 

Easy to install, easy to use! Delivers ultra-precise results immediately to your inbox.

  • Monitors AC power (or DC power),  but also your process parameter like speed or flow, with additional  analog AC/DC channels
  • Enhances the power diagnostic by also measuring the environment conditions with advanced EnviroSensor probes
  • Your campaign measurements are stored for years, and continuously stored as 1 min (min/max/average) trends daily, or 5 min trends, weekly or monthly. No gaps, you don’t miss a single cycle
  • You can store several thousands of events (32 GB flash memory)
  • Extensive library of waveform triggers on voltage magnitude, voltage HF impulses, frequency, currents inrush , AC/DC channels, and more.
  • All measured parameters are available every half-second in real-time (via ModbusTCP/IP, DNP3.0  or SNMP)
  • Trends and events can be quickly accessed using your Internet browser – no software needed
  • Interface available in more than 13 languages– the graphs can be delivered in two simultaneous languages (ideal for international teams)


Do you want to perform a connected load study to determine whether new loads and breakers can be added to a panel?  Or do you need to comply with California Office of Statewide Health Planning and Development (OSHPD) load study requirements?  If you answered "yes" to any of these questions, go the the GMC-1-PROSyS tab for your answer 

Do you want to monitor energy use, power consumption or perform an energy study or audit, monitor circuit loading, or equipment behavior such as current draw and cycling?  If any of these are true, you'll need to power logger. Power consumption and energy use studies require monitoring of voltage and current, and then calculating the power in Watts, plus calculating energy consumption in kWh.  For these applications, we recooment the products under the Fluke tab.

Often power studies involve monitoring several loads or panels or multiple locations simultaneously. We can supply a single monitor or multiple monitors.

Power Analysis

Power Analysis (includes energy measurements)

Power Standards Lab

POWERetc has worked closely with Power Standards Labs to create two innovative products - availalble only from POWERetc. Both of these products are based on the world-class power analysis capbilities of the PSL PQube 3.  Depending on your requirements, one of these specialty instruments could be the perfect answer.

  • The PQube3-Pass-Thru is designed to quickly interface between a single-phase recepticle and a piece of electroinc equipment. It will immediaelt begin recording power quality data that can assist in determining if problems the equipment is have are power releated or not.  
  • The PQube3 Rugged is a three-phase power quality analyzer housed in a weather-proof enclosure and designed to be installed in remote locations. the device features cellular communications as well as traditonal internet to facilitate data gathering from remote locations

Coming Soon

In additon to these two specialized systems, the new PQube 3 Portable from PSL is the most advanced portable power quality and energy analyzer available.
