Voltage Data Loggers and Recorders
Voltage data loggers can be used for a wide variety of applications including monitoring energy consumption, detecting power drops and surges, and recording the low-voltage output of sensors. Voltage data loggers are available in both single and multi-channel versions, with options for monitoring AC voltage, DC voltage, or both — making them suitable for everything from utility submetering and power quality analysis to process signal recording and solar energy monitoring.
Voltage data loggers come with a wide variety of connection options including direct USB, USB cable, and wireless. Some models feature large LCD displays that allow you to view data in real time as it's recorded, while others are compact and designed for long-term unattended deployment.
MicroDAQ carries voltage data loggers from leading manufacturers including HOBO, Lascar, ACR Systems, VersaLog, Monarch, TandD, and more, giving you multiple options for virtually any application. Our non-commissioned Technical Sales Representatives are available by chat, email, or phone and are always happy to help you find the best solution for your particular needs. MicroDAQ also provides ISO/IEC 17025:2017 accredited calibration services for DC voltage measurement equipment from 0.8 mV to 1,020 V and DC current from 0.006 mA to 11 A.
