AT4732AH Multi-Channel Temperature Tester — High Voltage Live Testing Edition

The AT47AH series has been upgraded to the AT47AH series, representing an iterative upgrade within the same product line. The instrument features a high-performance ARM9 microprocessor for control and real-time high-speed data acquisition. The newly upgraded touch mirror panel utilizes the 9th generation ATOS operating system, supporting both Chinese and English interfaces for intuitive operation, enhanced usability, and greater intelligence.

The redesigned AT47AH series comes with a built-in 64GB ultra-large memory, USB communication mapping, and real-time FPGA circuitry that breaks through sampling rate limitations. Combined with high-efficiency, high-precision analog circuits, it achieves high-precision and ultra-high-speed sampling with a test temperature resolution improved to 0.01°C. The instrument features channel isolation voltage of 2000VDC and 1000VAC (full isolation of digital and analog signals), making it suitable for complex systems requiring simultaneous temperature and voltage monitoring, such as new energy, automation control, and other applications.

The instrument is equipped with built-in LAN, RS232, USB-232, and VCOM virtual serial ports. The RS-232 and USB-232 interfaces support the Modbus (RTU) protocol, while the LAN port supports the Modbus (TCP) protocol. It enables instrument control and data acquisition via computer, effectively applied to remote control, data acquisition, and analysis.

The instrument supports USB communication, and data acquisition, analysis, and printing can be achieved through the included computer software. It supports USB disk storage for real-time sampling data storage. Users can perform independent calibration for each channel.
