The newly upgraded AT4508 is a multi-channel temperature tester controlled by an ARM microprocessor. It supports parallel multi-channel testing, acquiring, alarming and transmitting data for eight temperature channels simultaneously. It is compatible with a wide range of temperature sensors with fast response and stable data, and includes thermocouple break detection.
Using an advanced measurement principle, the instrument achieves 0.1 °C temperature resolution and broad adaptability, supporting K/N/E/J/T/R/S/B type thermocouples over a range of -200 °C to 1300 °C.
The AT4508 runs the independently developed Onmeas ATOSTv4 operating system, making operation simpler and more convenient; with ATOSTv4 the instrument works well with large-capacity storage and offers powerful PC communication. RS-232 and USB interfaces are provided as standard together with free communication software, so data acquisition, analysis and printing can be carried out easily from a PC.
The instrument uses a rugged, vibration-resistant enclosure for use in harsh environments, and its fully isolated digital and analogue signals allow live testing (isolation voltage 350 VDC, 230 VAC) safely and reliably. The AT4508 comes standard with a USB flash drive interface supporting real-time data storage.
