Tuner Electronics Testing Labs Certification CEC DOE Third-party testing and authentication services

Provide various AV/IT products testing and certification

With the advent of the Internet era, IT/AV multimedia has become an indispensable part of people's life, and its security, electromagnetic compatibility and reliability issues have become the focus of manufacturers and consumers.

Product range:

Radio, television, combination stereo, active speaker, tuner, Karaoke, sound mixer, video recorder, language repeater, television, monitor, Projector, TV antenna amplifier, video modulator, frequency converter, audio and modem, satellite television broadcasting receivers, set-top boxes, digital TV receiver, electronic organ, central processing unit (CPU), printers, monitors, scanners, picture-tel, fax, telephone switches, transponder, radio and television transmission receiving equipment, pagers, separation device, rotary steam Type DRYER, ENGRAVING machine, LASER cutting machine, SAwing machine and SLicing machine, CENTRIFUge, injection machine, oven and heating furnace, ion implantation machine, microscope, measuring and testing instruments, color separators, spectrometers, optical ray equipment, word processors, etc.

With the progress of technology, some electronic tuners also have metronome function, and added audio interface, can provide internal signal transmission for electroacoustic instruments, making the sound of electroacoustic instruments become more convenient, even in a very noisy external environment can also not be interfered. This type of tuner is also known as the "three-in-one electronic tuner".
