AT4108 is an economical multi-channel temperature measurement instrument developed by ONMEAS Instruments. It utilizes an ARM microprocessor to control multi-channel scanning tests, simultaneously collecting, alarming, and transmitting data from 8 temperature channels. Compatible with a variety of temperature sensors, it offers fast response and stable readings, and features thermocouple open-circuit detection.
Using advanced measurement technology, the AT4108 achieves a temperature resolution of 0.1°C.
The AT4108 offers broad compatibility, supporting K/J/T type thermocouples with a measurement range from -200°C to 1300°C.
It runs on the proprietary ONMEAS ATOS v4 operating system, making instrument operation simpler and more convenient. Leveraging ATOS, the instrument is fully compatible with large-capacity storage and delivers powerful PC communication capabilities.
The instrument comes standard with RS-232 and USB interfaces, and includes free communication software for easy data acquisition, analysis, and printing via PC.
