The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A, AT4764A) multi-channel temperature testers feature a high-performance ARM microprocessor, 64GB built-in storage, and a 7-inch capacitive LCD touchscreen for easy viewing of temperature values, temperature variation curves, bar charts, and more.
They can simultaneously collect multi-channel temperature data, with high/low alarm notifications and communication transmission.
The AT47A series supports up to 64 temperature measurement channels, compatible with K, N, E, J, T, R, S, and B type thermocouples, offering fast response and stable readings. Broken thermocouple detection is also built in. Each channel can be individually configured and calibrated.
The instrument supports USB communication. Data acquisition, analysis, and printing can be performed through the included computer software. USB flash drive storage is supported for real-time sampling 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) for safe and reliable operation.
