The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A, AT4764A) multi-channel temperature tester features high-performance ARM microprocessor control, built-in 64GB storage, 7-inch capacitive LCD display, and touchscreen operation for easy viewing of temperature values, temperature change curves, bar charts, etc.
It can simultaneously collect multi-channel temperature data, with upper and lower limit alarms and communication transmission.
The AT47A series can collect up to 64 temperature data channels, compatible with K/N/E/J/T/R/S/B type thermocouples, with fast response speed and stable data, and also features thermocouple disconnection detection. Each channel can be set and calibrated independently.
The instrument supports USB communication, and through the standard computer software, data acquisition, analysis, and printing can be achieved. It supports USB disk storage for real-time storage of sampling data. Users can calibrate each data channel independently.
The AT47A series uses fully isolated digital and analog signals, enabling live testing (isolation voltage 350VDC, 230VAC), ensuring safety and reliability.
