DTU Handheld In-the-field calibration traditionally required bulky instruments and long setup times.
The DTU Handheld Terminal is a portable industrial data communication device designed for field deployment, on-site maintenance, and mobile data acquisition. It integrates serial communication (RS232/RS485), cellular connectivity, and edge processing capabilities, allowing technicians to directly interface with equipment, read parameters, upload data to the cloud, and perform diagnostics in real time. It is widely used in SCADA, industrial IoT, asset inspection, and remote device commissioning.
