The newly upgraded AT4524 is a multi-channel temperature tester controlled by an ARM microprocessor, adopting multi-channel parallel testing, simultaneously collecting, alarming, and transmitting data from 24 channels. Compatible with multiple temperature sensor types, fast response, stable data, with open thermocouple detection function.
AT4524 adopts advanced testing principles, achieving a temperature resolution of 0.1°C. It offers wide adaptability, supporting K/N/E/J/T/R/S/B type thermocouples. Test range from -200°C to 1300°C.
The instrument comes standard with RS-232 and USB interfaces, providing free communication PC software for easy data acquisition, analysis, and printing.
The AT4524 features a rugged and vibration-resistant housing, capable of working in harsh environments. Fully isolated digital and analog signals, supports live testing (isolation voltage 350VDC, 230VAC), safe and reliable. The AT4524 comes standard with a USB disk interface for real-time data storage.
