DC, AC ELF, RF EMF Surveys & EMI/RFI Measurements

VitaTech Engineering performs DC, AC ELF & RF EMF (Electromagnetic Field) Surveys and EMI/RFI (electromagnetic interference/radiofrequency interference) Measurements throughout the United States and around the world. Our trained EMF(electromagnetic field) engineering staff uses only state-of-the-art factory-calibrated instruments. All electromagnetic field surveys are well documented (some sites are videotaped during data collection) and our final engineering reports are the most comprehensive in the industry.

VitaTech designs, installs and tests magnetic shielding systems to attenute DC, AC ELF, VLF, LF, MF, & HF (0 Hz - 30 MHz) magnetic fields responsible for electromagnetic interference (EMI) in sensitive electronic equipment and instruments, and RF shielding systems to attenute 30 kHz - 100 GHz electric field and planewave/microwave RF emissions responsible for radiofrequency interference (RFI) problems. VitaTech is one of the few EMF shielding companies in the world that guarantees final shielding performance.

It should also be noted that VitaTech Engineering is a completely independent, unbiased, EMF Survey & EMI/RFI Measurement, Exposure & Risk Assessment, Magnetic and RF shielding company.

VitaTech offers Full Spectrum DC, AC ELF & RF EMF Surveys and EMI/RFI Measurements of research laboratories (i.e., TEM, SEM, I-BEM, etc.), nanotechnology facilities under development, universities & schools, commercial buildings, hospitals, MRIs/clinics, industrial smelters & sites, military bases & federal government buildings (GSA), cruise/merchant/war ships, electric rails systems (i.e., subways, light rail, trains, MAGLEVs, etc.) and special scientific research projects.
