Advanced Power Measurement and Analysis


The MEATROL MQ31 Power Quality Analyzer is a cutting-edge device designed for comprehensive power quality analysis and energy measurement. With its robust Rogowski coil and voltage-output current clamp current sensors, this analyzer is capable of capturing accurate data across a wide range of electrical parameters, including current, voltage, power factor, harmonic, active power, and electric energy. The device’s versatility extends to single-phase and three-phase systems, making it suitable for a variety of applications, from home energy reviews to industrial power monitoring.

Efficient Data Collection and Storage
The MEATROL MQ31 Power Analyzer is equipped with a high-capacity 16GB Micro SD card, allowing for extended data storage and easy USB DISK Download. With a standard storage interval of 1 minute, users can collect and store up to 3 years’ worth of data, ensuring that they have a comprehensive record of their power usage. The device’s ability to record voltage swell, voltage dip, and three-phase unbalance events is particularly useful for identifying and troubleshooting power quality issues.

Seamless Integration and Communication
The MEATROL MQ31 Power Analyzer is designed for seamless integration with various systems, thanks to its standard RJ45 and RS485 communication interfaces. The device supports Modbus TCP and Modbus RTU protocols, enabling real-time data transmission to centralized systems. This feature is particularly beneficial for engineers and maintenance personnel who need to monitor and analyze power quality remotely. The MEATROL MQ31’s compatibility with 4G Gateway technology also allows for data transmission to the Cloud, ensuring that users have access to their power data from anywhere.
