UT323 Digital Thermometer

The UT323 Digital Thermometer is a professional contact-type temperature measurement instrument designed for engineers, electricians, HVAC technicians, and laboratory professionals. This thermometer uses external thermocouple probes to provide highly accurate temperature readings in industrial, scientific, and maintenance environments. As a result, technicians can monitor temperature changes in electrical equipment, manufacturing systems, and HVAC installations with precision.

Moreover, the UT323 Digital Thermometer supports several thermocouple types including K, J, T, E, R, S, and N, which makes the device extremely versatile for different measurement tasks. Because each thermocouple type supports a different temperature range, technicians can select the appropriate probe depending on the application requirements.

In addition, the thermometer provides a single temperature input channel (T1) that connects to a thermocouple probe for contact temperature measurement. This design ensures stable readings and accurate monitoring of temperature conditions in industrial processes, heating systems, and laboratory experiments.

Furthermore, the UT323 Digital Thermometer offers a very wide temperature measurement range depending on the thermocouple 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 range, technicians can use the device for many professional tasks such as furnace monitoring, electrical diagnostics, HVAC maintenance, and industrial equipment inspection.

Another important advantage of this thermometer is its advanced monitoring functions. The device includes MAX, MIN, and AVG measurement modes, which allow users to track temperature variations over time. In addition, the thermometer features high and low temperature alarms, which alert technicians when the measured temperature exceeds preset limits.

The device also includes data logging capability, allowing technicians to store up to 100 temperature readings in memory. Furthermore, the USB interface allows users to transfer stored measurements to a computer for analysis and documentation. These features help engineers generate inspection reports and analyze temperature performance during maintenance operations.

Because of its professional performance, reliable measurement accuracy, and durable industrial design, the UT323 Digital Thermometer is widely used in electrical maintenance, HVAC diagnostics, industrial process monitoring, and laboratory temperature testing.
