High Precision Measurement Accurate sensing: Built-in high-precision electric/magnetic field composite sensor with high sensitivity and fast response, capable of capturing weak electromagnetic field changes. Wide range: electric field measurement range up to 0.01V/m-100kV/m, magnetic field measurement range up to 1nT-20mT, to meet the measurement needs of different scenarios. High resolution: the minimum display resolution reaches 0.1V/m or 0.1nT, ensuring the accuracy of the measurement data. Multi-functional display Real-time display: Equipped with a large-size LCD screen, it displays the measured electromagnetic field strength value in real time, supports the direct display of magnetic flux density value (e.g. W/m), and can switch between peak value or average value display. Graphical display: some models support automatic drawing of magnetic field waveform distribution graph, intuitively show the trend of electromagnetic field changes. Intelligent operation One-button measurement: easy and convenient operation, users only need to press the power switch, set the measurement mode, and then quickly obtain the measurement results. Data storage and export: Built-in large-capacity memory can record a large amount of measurement data and support data export to computer for further analysis via USB interface. Portability and Durability Lightweight and portable: compact design and light weight, easy to carry to different locations for on-site measurement. Rugged: Made of high-quality materials, the housing is durable and can withstand harsh environments. Safety and Compliance Compliance: The instrument complies with the relevant electromagnetic radiation protection standards at home and abroad to ensure the authority and reliability of the measurement results. Safety Alert: When the electromagnetic field strength exceeds the preset safety threshold, the instrument will sound an alarm to remind the user to take appropriate measures.
