The newly upgraded AT4508 is an ARM microprocessor-controlled multi-channel temperature tester featuring multi-channel parallel testing that simultaneously collects, monitors, and transmits data for 8 temperature channels. It is compatible with various temperature sensors, offers fast response and stable readings, and includes thermocouple break detection.
The AT4508 utilizes advanced measurement principles to achieve a temperature resolution of 0.1°C. It offers wide adaptability, supporting K/N/E/J/T/R/S/B type thermocouples, with a measurement range from -200°C to 1300°C.
The AT4508 operates on the proprietary Onmeas ATOSTMv4 operating system, making instrument operation simpler and more convenient. Thanks to ATOSTMv4, the instrument is fully compatible with large-capacity storage and features powerful PC communication capabilities.
The AT4508 features a rugged, vibration-resistant enclosure for operation in harsh environments. Fully isolated digital and analog signals enable live testing (isolation voltage 350VDC, 230VAC), ensuring safety and reliability. The AT4508 comes standard with a USB drive interface for real-time data storage.
