AT4748AV Multi-Channel Temperature Tester - Multi-Function Data Acquisition

The AT47AV series has been upgraded to the AT47AV series, an iterative upgrade within the same product line. The instrument features a high-performance ARM9 microprocessor for real-time high-speed data acquisition. The newly upgraded touchscreen mirror panel is equipped with the Onmeas ATOS version 9 operating system, supporting both Chinese and English interfaces for intuitive, easier, and smarter operation.

The newly designed AT47AV series comes standard with 64GB large internal memory, communication-mapped USB drive, and real-time FPGA circuitry that overcomes sampling rate limitations. Combined with high-efficiency, high-precision analog circuitry, it achieves high-accuracy and ultra-high-speed sampling with a temperature measurement resolution of 0.01°C. The instrument channel isolation voltage is 350VDC / 230VAC (full isolation of digital and analog signals), suitable for complex systems requiring simultaneous monitoring of temperature and voltage, such as new energy, automation control, and other fields.

The instrument features 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. The instrument can be controlled and data acquired via computer, effectively applied to remote control and data acquisition and analysis.

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