Description
Overview
GAOTek portable handheld precision voltmeter is a handheld precision AC current pressure gauge that can accurately measure the range of 20 mV to 10 V small-signal voltages, and the AC voltage measurement capability is better than 8-digit semi-high-precision standard digital multi meter.
