WY1972A Digital dual channel AC millivolt meterDetailed product description：

The WY1972A digital dual channel AC millivolt meter consists of a high stability amplifier composed of an integrated circuit and transistors, as well as a liquid crystal display circuit. The large LCD displays clear and intuitive readings, with an input impedance of up to 10M Ω, ensuring the measurement system's error and enabling accurate measurement of AC voltage. The input of this machine can be set as floating or grounded. Floating input measurement is particularly suitable for ensuring safety in balanced conveying, tuning indication, potential difference measurement, and high voltage measurement.
