Introduction
The DTS-MUB Portable Smart Refrigerated Calibration Bath is a high-precision automatic temperature calibration device. The unit is compact and lightweight, featuring a press-type quick-seal structure that prevents leakage, making it suitable for on-site transportation. Equipped with a 5-inch high-definition touch screen, it supports multi-segment program temperature control and one-click automatic calibration. The device integrates a high-precision electrical measurement module and is equipped with an independent standard channel and multiple DUT (Device Under Test) channels. It is compatible with thermocouples, RTDs, temperature transmitters, temperature switches, etc. It can synchronously acquire temperature field and measured data, display various testing parameters in real time, automatically determine instrument conformity, support full lifecycle management of sensors, and generate standard calibration reports. It features built-in large-capacity storage, capable of storing over 100,000 records with retrieval support. Combined with hierarchical permission management, it meets the needs of on-site integrated verification and data traceability. It is widely used for on-site verification and calibration of various temperature sensors.
