TH3422 4-Channel Power Meter with Waveform & Harmonic Analysis

AC/DC Power Meters typically feature a clear and easy-to-read display that shows the measured parameters in real-time. The display may include digital readouts, bar graphs, and waveform displays for comprehensive visualization. Additionally, advanced power meters allow for data logging, where measurement values can be recorded and stored for later analysis. This feature is particularly useful for monitoring power usage over time, identifying peak loads, and assessing the efficiency of electrical systems.

Features

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

Application

Power supply: AC power supply, DC power supply, linear power supply, switching power supply, inverter

New energy: solar batteries, new power cars, electric bicycles

Company Profile

Overview

Changzhou Tonghui Electronic Co. Ltd. was founded in 1994. It is a provincial high-tech enterprise integrating R&D, manufacturing and marketing. It is located in the National Development Zone – Changzhou Hi-tech Industry Development Zone with superior geographical position and beautiful natural environment. Covering a land area of 38000 m2 with construction area of 3000 m2. The company has more than 200 employees. More than 75% have college education or above. R&D personnel takes up more than 25% of total employees, and annual R&D investment exceeds 10% of company’s annual revenue.

For the past more than 20 years, Tonghui has been devoting itself to the research and development of electronic measurement instruments. Bearing the faith of technology first, we are struggling to promote the development of domestic measurement instruments and minimize the distance with the world advanced instruments. The company establishes “Changzhou electronic component measuring instrument engineering research center”, which has undertaken the ministry/province/city/district science and technology project for many times, and won the provincial/city science and technology progress award for many times. As a result of years of effort, Tonghui has grown to be a well-known brand in electronic instrument industry.

Now we have developed the following products: Electronic component parameter test instrument, Winding component test instrument, Cable harness test instrument, Electrical safety test instrument, Resistance test instrument, Power electronic testing instrument, Data acquisition/recorder, Digit multimeter, and other instruments, as well as accessories and software products. Tonghui insists to provide users with creative solutions for more efficient measurement and higher product quality. Tonghui has a mature quality control system and strong product manufacturing and quality assurance team, to ensure that the products delivered to customers can meet the unified quality standards.

“To achieve customer satisfaction” is the principle that Tonghui always adheres to. Over the years, Tonghui has been striving to build a multi-level marketing system, integrating direct marketing, agency and network sales. We have also established an after-sales service system in more than 20 provinces and cities in China, which helps better serve our customers, and listen to customers.

At present, the overseas market has become an important part of the development of Tonghui business. Tonghui has gradually integrated the technology and experience accumulated over the years into the international competition system. It has established marketing systems in North America, Europe, Southeast Asia and South Asia and has achieved fruitful results, enabling high-tech products from China to meet the needs of worldwide customers. Meanwhile, we can continue to enrich our experience in the exchange of learning with international counterparts. Looking forward to the future, Tonghui will fully expand overseas resources and realize the same value in all aspects.

In 2015, Tonghui was successfully listed on National Equities Exchange and Quotations (stock code: 833509). With the help of the capital market, Tonghui will open a new chapter of healthy development. Tonghui will always be your reliable friend and always look forward to sharing success and future with you.
