ATQ4900

200-Channel Temperature Recorder

NewCategoryMulti-Channel Temperature Tester SeriesATQ49XX Series

The all-new upgraded AT4900 series multi-channel temperature tester features a high-performance ARM9 microprocessor for real-time high-speed data acquisition. Equipped with a 7-inch high-brightness capacitive touchscreen, it combines full-touch operation with auxiliary function keys, running the 7th generation ATOS operating system for enhanced usability and intelligence. The bilingual Chinese/English interface provides real-time measurement data and curve visualization for a completely new instrument experience.

The newly designed AT4900 series supports USB Type-C communication with USB flash drive mapping, and optional RS232/RS485/CAN/LAN interfaces. Utilizing real-time FPGA circuitry, it overcomes sampling rate limitations. Combined with high-efficiency, high-precision analog circuits, it achieves both high accuracy and ultra-high-speed sampling, with temperature measurement resolution improved to 0.01°C.
