Energy consumption data is invaluable in energy management and conservation. Therefore, electrical power meters are considered essential tools in households, offices, and industrial settings. Note that such energy usage monitors measure the electrical power of single devices or entire buildings and can be used to verify different energy parameters.

Interestingly, there are different types of electrical power meters. To provide an example, some highly sophisticated utility units are installed by power companies to measure energy consumption and costs. For those who prefer a customized look of their energy consumption at home, there are plug-in USB models and even entire household devices. While plug-in units can be inserted into sockets to measure individual appliances, some power meters can be linked to a building’s electric box to provide readings of the entire building’s energy, power, and voltage consumption. Furthermore, power monitoring systems that use a series of components and apps that measure home energy use are also available on the market.Electric usage monitors are invaluable in numerous settings and can help to reduce energy consumption throughout the globe. Before choosing a unit, however, prospective buyers should consider three major factors: requirements, specifications, and total costs.

Requirements: Firstly, users should refine their requirements in order to choose an electrical power meter (either a plug-in meter or an entire household energy reader). Note that when it comes to single-appliance devices, such power meters are ideal for people who rent and do not have access to the main circuit breaker box.

Specifications: Some of the main parameters to look for in an electrical power monitor are accuracy, functionality, and customizable measurement periods. Good USB power models, for example, should be able to track not only energy consumption but real voltage and current to make a proper diagnosis. Units should be able to track and record energy usage over time to help users develop energy-saving plans. To provide an example, power meters with customizable measurement periods can help to conduct measurements at different hourly rates (e.g., peak hours and nighttime). Some units can even make calculations for periods of up to 12 months, depending on changes in prices and tax. Last but not least, some smart power meters can control the measured device (e.g., shut it off) based on different setting schedules in order to save energy and cut down expenses.

Total costs: Given the variety of electrical power meters for sale, it’s no surprise that prices can vary significantly. For example, models that can store multiple readings on a multi-mode display and entire monitoring systems can be more costly than plug-in models.Due to the abundance of units for sale, choosing an electrical power meter can be a challenging task. Therefore, based on different connectivity, functionality, and installation specifications, as well as user reviews, we provide a list with some of the best meters available on the market.
