AT4708AH Multi-channel Temperature Tester - High Voltage Live Testing Version

The AT47H series has been upgraded to the AT47AH series, an iterative upgrade within the same product line. The instrument features a high-performance ARM9 microprocessor with real-time high-speed data acquisition. The newly upgraded touchscreen full-mirror panel uses Onmeas ATOS v9 operating system, supporting Chinese and English interfaces for intuitive, easier, and smarter operation.

The newly designed AT47AH series comes standard with 64GB built-in memory, communication-mapped USB drive, and real-time FPGA circuits that break through sampling rate limitations. Combined with high-efficiency, high-precision analog circuits, it achieves high-precision and ultra-high-speed sampling, with temperature measurement resolution improved to 0.01°C. The instrument features channel isolation voltage of 2000VDC and 1000VAC (fully isolated digital and analog signals), suitable for complex systems requiring simultaneous temperature and voltage monitoring, such as new energy, automation control, and other fields.

The instrument features built-in LAN, RS-232, USB-232, and VCOM virtual serial ports. The RS-232 and USB-232 interfaces support Modbus (RTU) protocol, and the LAN port supports Modbus (TCP) protocol. Computer-based control and data acquisition enable efficient remote control, data collection, and analysis.

The instrument supports USB communication, with included computer software for data acquisition, analysis, and printing. USB disk storage is supported for real-time sampling data storage. Users can perform independent calibration for each channel.
