UT322 Digital Thermometer

The UT322 Digital Thermometer is a professional contact-type temperature measurement instrument designed for engineers, electricians, laboratory technicians, and industrial maintenance professionals. This thermometer uses external thermocouple probes to measure temperature accurately in a wide range of industrial and scientific applications. As a result, technicians can monitor temperatures in electrical equipment, HVAC systems, manufacturing processes, and laboratory environments.

Moreover, the UT322 Digital Thermometer supports dual thermocouple inputs (T1 and T2), which allows technicians to measure two temperatures simultaneously. This dual-input capability makes the device very useful when comparing temperature differences between two points, such as inlet and outlet temperatures in HVAC systems or heating equipment.

In addition, the thermometer supports several thermocouple types including K, J, T, and E, which allows users to adapt the instrument for different measurement environments. Because different thermocouple probes support different temperature ranges, technicians can choose the appropriate probe for their specific application.

Furthermore, the UT322 Digital Thermometer provides a very wide measurement range depending on the probe type. For example:

• K-type thermocouple: −200°C to 1372°C

• J-type thermocouple: −210°C to 1200°C

• T-type thermocouple: −250°C to 400°C

• E-type thermocouple: −150°C to 1000°C

Because of this wide temperature capability, technicians can use the thermometer for electrical diagnostics, furnace monitoring, industrial maintenance, and laboratory testing.

Another important advantage of this device is its data logging capability, which allows storage of up to 100 temperature records. In addition, the USB interface allows users to transfer stored measurements to a computer for further analysis and reporting. These functions help engineers document temperature readings during inspections and maintenance work.

The thermometer also includes practical features such as MAX/MIN/AVG measurement modes, data hold function, backlit LCD display, and automatic power-off. These features help technicians analyze temperature variations and read values clearly even in low-light environments.

Because of its professional measurement capabilities and reliable design, the UT322 Digital Thermometer is widely used for industrial maintenance, HVAC system inspection, electrical diagnostics, and laboratory temperature measurement.
