The newly upgraded AT4824 is a handheld multi-channel temperature tester controlled by an ARM microprocessor. It adopts 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.
Advanced testing principles enable a temperature resolution of 0.1°C.
The AT4824 handheld multi-channel temperature tester offers wide adaptability, supporting K/N/E/J/T/R/S/B type thermocouples. Test range from -200°C to 1800°C.
The instrument comes standard with a USB interface and provides free communication PC software for easy data acquisition, analysis, and printing.
The AT4824 features a rugged and vibration-resistant housing, capable of working in harsh environments. Fully isolated digital and analog signals, supports live testing (isolation voltage 230V rms, 350VDC), safe and reliable. The AT4824 comes standard with a USB disk interface for real-time data storage.
