AT4756A Multi-Channel Temperature Tester

The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A, AT4764A) multi-channel temperature testers feature high-performance ARM microprocessor control with built-in 64GB storage and a 7-inch capacitive LCD touchscreen display for convenient viewing of temperature values, temperature curves, bar charts, and more.

The testers can simultaneously perform multi-channel temperature data acquisition, high/low limit alarming, and communication transmission.

The AT47A series supports up to 64 temperature data channels and is compatible with K/N/E/J/T/R/S/B type thermocouples, offering fast response and stable data, with thermocouple break detection capability. Each channel can be independently configured and calibrated.

The instrument supports USB communication, enabling data acquisition, analysis, and printing through the included PC software. USB drive storage is supported for real-time sampling data logging. Users can independently calibrate each channel's data.

The AT47A series employs fully isolated digital and analog signals, enabling live testing (isolation voltage 350VDC, 230VAC) for safe and reliable operation.
