Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
■ TH2281 series UHF digital millivolt/power meter, its test frequency range covers 9kHz~3GHz, thus filling the blank of voltage measurement in the low frequency band to the microwave band measurement of the full range coverage. Its equipped coaxial detectors and probes are indispensable tools for RF and microwave laboratories, test departments, and maintenance departments, and are thus widely used in factories, research departments, troops and schools.
