Product details
EM93 Electromagnetic Radiation Analysis and Detection InstrumentScope of application
Commonly used for measuring electromagnetic radiation from mobile communication base stations, broadcasting and television, medical equipment, radar, satellite communication equipment, pager stations, heat sealers, drying equipment, and microwave heating equipment.
EM93 can meet the requirements for measuring ultra-high frequency (ultra short wave) and microwave radiation.
EM93 is divided into three types: EM93A, EM93B, and EM93C, and the probes of each model of instrument are not exactly the same:
-EM93A consists of HF-60105 in the 1MHz-9.4GHz frequency range and HL60100 probe in the 680MHz-10GHz frequency range;
-EM93B consists of EM93A and BL30100E probes;
-EM93B consists of EM93A and BL30100E probes.
