ZHK2720 Electromagnetic Radiation Analyzer

The ZHK2720 Electromagnetic Radiation Analyzer is an instrument used for monitoring electromagnetic fields across power frequency, low frequency, high frequency, ultra-high frequency, microwave, and radio frequency ranges. It can accurately and quickly measure various complex electromagnetic environments. By changing the probe, it can measure the electric field strength, magnetic field strength, magnetic induction strength, and power density across different frequency ranges.

This analyzer is suitable for monitoring electromagnetic fields in various industries, including environmental protection, electric power, occupational health, and green buildings. The main unit is equipped with a radio frequency probe that can monitor RF electromagnetic radiation from communication base stations, broadcast television, radar, wireless communication, and more within its measurement range. Additionally, it is equipped with a low-frequency electromagnetic field probe to monitor low-frequency electromagnetic environments around AC substations, high-voltage transmission lines, various furnaces, induction furnaces, rail transit systems, and charging stations.
An optional portable RF electromagnetic field calibrator is available for quick on-site calibration of the instrument, ensuring the accuracy of measurement results.
