AT4708A Multi-Channel Temperature Tester

The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A, AT4764A) multi-channel temperature testers are controlled by a high-performance ARM microprocessor, featuring built-in 64G memory and a 7-inch capacitive touch screen. It allows easy viewing of temperature values, temperature change curves, bar charts, etc., while simultaneously collecting multi-channel temperature data with upper/lower limit alarm and communication transmission. The AT47A series can collect up to 64 channels of temperature data, compatible with K/N/E/J/T/R/S/B type thermocouples, offering fast response, stable data, and broken-thermocouple detection. Each channel can be independently configured and calibrated.

The instrument supports USB communication, enabling data acquisition, analysis, and printing through the included computer software. It supports USB disk storage for real-time data storage. Users can independently calibrate each channel.

The AT47A series features fully isolated digital and analog signals, allowing live testing (isolation voltage 350VDC, 230VAC) — safe and reliable.
