Tonghui Th3421 Multi-Channel Digital Power Meter Channel Combination: Optional 3/4 Channels

https://ckt2017.en.made-in-china.com/contact-info.html
Brief Introduction

Channel combination: optional 3/4 channels
AC and DC test
High stability and consistency: adopt phase-locked loop frequency 
 multiplication synchronization control and power synchronization setting
High resolution display: 7-inch 800×600 resolution touch screen, support mouse operation
Display screenshot function
Broadband input: 45Hz-420Hz, suitable for most power systems on the market
Embedded system: equipped with embedded operating system, human-
 computer interaction is more flexible and friendly
Comparison function: provide comparison output of 8 comparison 
 channels, and the output mode is programmable
Harmonic analysis: controllable analysis parameters, providing list display 
 and bar graph display
Waveform display: input signal waveform/integrated power waveform
Vector display: vector display of input signal
Flexible energy integration control: provide continuous time control and 
 manual control the running and stopping of energy integration
File storage: relatively powerful file system, compatible with most U disks
Protocol: SCPI instruction set and MODBUS instruction analysis
