Multi-Channel Temperature Tester (High-Precision Version)

Contains 8 products CategoryMulti-Channel Temperature Tester

The newly upgraded AT47A series (AT4708A, AT4716A, AT4724A, AT4732A, AT4740A, AT4748A, AT4756A and AT4764A) multi-channel temperature tester is controlled by a high-performance ARM microprocessor and has 64 GB of built-in storage. Its 7-inch capacitive LCD with touch operation makes it easy to view temperature values, temperature curves and bar charts, and it can acquire multiple temperature channels simultaneously with over/under alarm and communication functions. The AT47A series can acquire up to 64 temperature channels and supports K/N/E/J/T/R/S/B type thermocouples with fast response and stable data, plus thermocouple break detection; each channel can be configured and calibrated independently.

The instrument supports USB communication, and the supplied PC software enables data acquisition, analysis and printing; a USB disk storage function records sampled data in real time, and users can calibrate each channel independently.

The AT47A series uses fully isolated digital and analogue signals for live testing (isolation voltage 350 VDC, 230 VAC), making it safe and reliable.
