AT4740AV Multi-channel Temperature Tester Multi-functional Data Acquisition

The AT47AV series has been upgraded to the AT47AV series, as an iterative upgrade of the same series. The instrument is controlled by a high-performance ARM9 microprocessor with real-time high-speed data acquisition. The newly upgraded full mirror touch panel uses Onmeas' 9th generation ATOS operating system, supporting both Chinese and English interfaces, making operation intuitive, easier and smarter.

The newly designed AT47AV series comes standard with 64G large internal memory, communication mapped as USB drive. Using real-time FPGA circuitry, it breaks through the sampling rate limitation. Combined with efficient, high-precision analog circuits, it achieves high precision and ultra-high-speed sampling, with temperature test resolution improved to 0.01°C. The instrument features channel isolation voltage of 350VDC, 230VAC (full isolation between digital and analog signals), suitable for complex systems requiring simultaneous temperature and voltage monitoring, such as new energy and automation control fields.

The instrument has built-in LAN interface, RS232, USB-232, VCOM virtual serial port. RS-232 and USB-232 interfaces support Modbus(RTU) protocol, and the LAN port supports Modbus(TCP) protocol. The instrument can be controlled and data can be collected through a computer, effectively used for remote control and data collection and analysis.

The instrument supports USB communication, and data collection, analysis and printing can be realized through the standard computer software. It supports USB disk storage for real-time storage of sampled data. Users can independently calibrate each channel.
