UNI-T UT3224+ Multi-channel Temperature Measuring Device (-200~1800°C; 24CH)
The UT3224+ is a professional 24-channel temperature measuring instrument designed for continuous multi-point monitoring in production and laboratory environments. Its user interface emphasizes clarity and control: measurements are shown as numeric values, realtime curves and histograms so operators can quickly grasp both individual readings and overall trends. The unit accepts a broad range of thermocouple types so it can be adapted to many sensor choices and test conditions.
Engineered for stability and repeatability, the instrument stores logged data to USB for easy archival and transfer, includes on-screen alarms for out-of-range channels, and supports remote data access over standard communication ports. The overall layout and handle design make it straightforward to install or move within a test bench or 2U cabinet, while onboard file-management simplifies saving and restoring measurement setups.
In practice the UT3224+ serves as a central recorder for simultaneous temperature checks across many points, helping technicians and engineers spot anomalies, validate processes, and keep long-term records. It’s targeted at production lines, R&D labs and quality departments that need reliable multi-channel temperature logging with easy data export.
