Voltage and Current Data Loggers and Recorders

Find a wide selection of highly accurate and reliable voltage and current data loggers from one of the leaders in data logger industry. MicroDAQ.com has been an authorized distributor of data loggers for over 18 years, carrying over 30 well-respected brands. Whether you're looking for a current data logger or a power meter that can measure, store and analyze up to 144 different power and energy parameters, we have models for every application and budget.

Voltage and Current Data Loggers

Current and voltage data loggers are used when you want to monitor and record voltage and amperage levels. They are available in AC and DC versions as well as for single and multiphase applications. They range from low voltage or current models used to monitor sensor outputs all the way up to large multi-circuit meters used to identify usage trends.

Energy and Power Meters

An energy meter is used to measure and record power consumption, and they can be used in both residential and commercial applications. These devices monitor and record different electrical parameters that can include volts, amps, watts, volt-amps (VA), volt-amps reactive (VAR), kilowatts (kW), kilowatt hours (kWH), power factor and harmonics. 

Multi-Circuit Power Submeters

Our multi-circuit power submeters let you monitor multiple independent loads without having to purchase individual energy meters. These devices can be integrated into building management systems and used to record and track tenant power consumption or monitor power consumption across multiple devices.
