The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A, AT4764A) multi-channel temperature testers feature high-performance ARM microprocessor control, built-in 64GB storage, and a 7-inch capacitive LCD touchscreen display.
The intuitive touchscreen operation makes it easy to view temperature values, temperature trend curves, bar charts, and more. The AT47A series can simultaneously collect multi-channel temperature data, with high/low alarm functions and communication transmission capabilities.
It supports up to 64 temperature channels and is compatible with K/N/E/J/T/R/S/B type thermocouples, delivering fast response and stable readings with built-in open-circuit detection. Each channel can be independently configured and calibrated.
The instrument supports USB communication, and the included computer software enables data acquisition, analysis, and printing. It supports USB disk storage for real-time data logging. Users can independently calibrate each channel.
The AT47A series uses fully isolated digital and analog signals, enabling live testing (isolation voltage: 350VDC, 230VAC), ensuring safety and reliability.
