Note: The images are of the HDM3075H, as both multimeters are visually comparable, except the HDM3075B lacks a GPIB port.
The Hantek HDM3075B is a 7½ digit benchtop multimeter with a 0.1pA current resolution and 10nV voltage resolution. The multimeter has both 3A and 10A front inputs, which can perform DC measurements up to 1000V, and True-RMS AC measurements up to 750V. Furthermore, the HDM3075B can perform math functions such as dB/dBm scaling, measurement statistics, and setting limits. The multimeter has a maximum reading rate of 50K readings per second; these can be viewed using the histogram or trend chart functions, which are helpful for transient analysis. The HDM3075B model includes LAN, USB-B, and RS232 interfaces, which can be used to remotely control the multimeter.
