Description

The Tonghui TH2848 series is a high-resolution impedance analyser with a 10.1-inch capacitive touchscreen (1280×800) and automatic auto-balance bridge technology for four-pole measurements; it covers test frequencies from 4 Hz to 10 MHz and offers an AC signal level of up to 20 VAC/100 mA and DC bias of up to ±40 V/±100 mA with a basic accuracy of 0.05 %.

With dual CPU architecture, it achieves measurement speeds of up to 400 measurements per second (2.5 ms) and supports spot measurement, list scan and graph-based scans with up to four parameters per trace, as well as powerful sorting and comparison functions.

In the Linux-based system with embedded help system, SCPI/MODBUS compatibility (including Keysight E4980), the device can be used in a variety of applications. (including Keysight E4980A, HP 4284A) and independent cylinder control (24 V), capacitors, inductors, resistors, piezoelectric and ceramic components as well as printed circuit boards, semiconductors and liquid crystal materials can be precisely characterised. The TH2848 series is ideal for laboratory and production environments where maximum stability, speed and versatility are required - from routine testing to materials research.
