Digital AC Millivoltmeter Dual Channel Millivolt Meter Tester Range 5Hz~12MHz


Overview:

The product is a 4½-bit LCD dual-channel digital AC millivoltmeter, which can also be used as a power meter and a level meter, and can display the measured frequency value at the same time, and can also be used as a frequency meter alone. Intelligent microprocessor control technology, excellent amplifier circuitry and A/D linear detector make the inherent error of measuring voltage better than 1%. SMD production and assembly process makes the millivoltmeter has small size, light weight, high stability and reliability, fast measurement speed, small frequency response error and other excellent performance.
