UNI-T UT701 Single Function Temperature Calibrator

UNI-T UT701 Single Function Temperature Calibrator

The UNI-T UT701 is a high-precision, single-function temperature calibrator designed for professional use in industrial temperature measurement and instrumentation verification. With a remarkable output accuracy of up to ±0.05%, the UT701 ensures precise sourcing and simulation of temperature-related parameters, making it ideal for calibration labs, field service engineers, and maintenance technicians.

This calibrator supports multiple output functions, including DC voltage, resistance, thermocouples (TC), and resistance temperature detectors (RTDs). It can simulate and measure a variety of thermocouple types—J, K, T, E, R, S, B, N, Wre325, and Wre526—as well as thermal resistance types such as Pt10, Pt100, Cu50, and Cu100, covering a wide temperature range from –200°C to 2300°C depending on the sensor type. The device also features high-accuracy cold junction compensation to ensure reliable thermocouple measurements.

The UT701 offers both manual and automatic stepping and ramping modes, including fast/slow ramp and fixed step output (e.g., 25% step-ramp), enhancing simulation capabilities in testing applications. These ramp and step functions are especially useful in validating the response of temperature control systems.

It features a 6-digit display with clear visibility and a compact design, measuring only 96 × 193 × 47 mm and weighing 410 g, making it highly portable. The instrument runs on a 9V battery (6F22) and comes with test leads, a protective cloth bag, and an English manual, packaged neatly in a gift box.

With CE and UKCA certifications, the UT701 meets international standards of safety and performance. Its intuitive interface, robust feature set, and reliable measurement accuracy make it an excellent choice for professionals involved in temperature system verification, calibration of transmitters, sensors, and temperature controllers.
