Uni-T UT320D Termómetro de Contacto de Canal Duplo

The Uni-T UT320D is a compact, high-precision dual-channel contact thermometer designed for professional temperature measurement across a wide range of applications. With support for multiple thermocouple types (K, J, T, E, N, R, S) and a measurement range from -250°C to 1767°C, it delivers accurate readings for demanding industrial, HVAC, and laboratory environments. The dual-input design allows simultaneous monitoring of two points and differential temperature (T1-T2) calculation, streamlining diagnostics and system analysis.

Advantages

Dual-channel measurement with T1-T2 differential function enables quick comparison and fault detection. High accuracy of ±(0.2% + 0.8°C) for most thermocouples ensures reliable data. The backlit LCD display and data hold, MAX/MIN/AVG recording functions enhance usability in low-light or fast-changing conditions. Rugged construction withstands drops up to 1 meter, making it suitable for field use.

Suitable for

• HVAC system diagnostics and maintenance
