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, a 7-inch capacitive LCD touchscreen display for easy viewing of temperature values, temperature curves, bar charts, and more.
The AT47A series can simultaneously acquire up to 64 channels of temperature data, with high/low alarm and communication capabilities. It is compatible with K, N, E, J, T, R, S, and B type thermocouples, offering fast response and stable readings, along with open thermocouple detection. Each channel can be individually 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 sampling data. Users can perform independent calibration on each channel.
The AT47A series utilizes fully isolated digital and analog signals, enabling live testing (isolation voltage 350VDC, 230VAC), ensuring safety and reliability.
