Tonghui TH3321 Power Meter

The Tonghui TH3300 series is a line of high-performance, single-channel digital power meters designed for fast, accurate, and detailed analysis of both AC and DC power systems. Featuring a vibrant 4.3-inch color LCD screen, these instruments provide a clear and intuitive user interface in both English and Chinese. By utilizing advanced PLL (phase-locked loop) technology, the TH3300 series ensures faster, more stable measurements. With rich display modes, waveform visualization, and powerful analysis functions, this series is an essential tool for R&D, quality control, and production testing across a wide range of industries.

Key Features

• Advanced Measurement Technology: Accurately tests both AC and DC power with a wide frequency response and a fast data update rate for capturing dynamic power behavior.
• Rich Display & Analysis: The large color screen offers multiple display modes, including a traditional four-window view and a full-screen parameter display. It can simultaneously show voltage and current waveforms for detailed analysis.
• Harmonic Measurement: Provides multiple display modes for harmonic analysis, including lists and histograms, to easily identify and troubleshoot power quality issues (not available on TH3311).
• High Precision: Delivers a high accuracy of 0.15% across a wide measurement range, ensuring reliable and repeatable results for demanding applications.
• Broad Applications: Perfectly suited for power efficiency testing of home appliances (TVs, air conditioners), industrial products (motors, chargers), lighting (LEDs), and new energy systems (photovoltaics, electric vehicles).
