Uni-T UT320D Dual Channel Contact Thermometer

The Uni-T UT320D is a professional dual-channel contact thermometer engineered for high-precision temperature monitoring. Designed to support both K and J type thermocouples, this device provides a versatile solution for measuring temperatures across a broad range. Its robust construction and compact form factor make it an essential tool for professionals working in industrial, laboratory, and HVAC environments who require reliable and accurate thermal data.

Advantages

This thermometer stands out due to its dual-channel capability, which allows for the simultaneous monitoring of two separate temperature points. The inclusion of a T1-T2 differential measurement function significantly streamlines diagnostic processes, particularly when assessing heating, ventilation, and air conditioning systems. With a fast sampling rate and high measurement accuracy, the device ensures that data is captured quickly and reliably. The integrated data hold, along with min, max, and average value recording modes, provides users with comprehensive tools for detailed thermal analysis in various professional settings.

Suitable for

• HVAC system diagnostics and maintenance
• Industrial equipment temperature monitoring
• Laboratory research and testing
• Quality control in manufacturing processes
• General temperature measurement in field service

This device may not be suitable for applications requiring non-contact temperature measurement, such as scanning large surfaces from a distance or monitoring moving objects where physical contact is impossible. It is also not intended for medical diagnostic purposes or environments with extreme electromagnetic interference that could affect thermocouple readings.

• Accuracy: ±(0.5% + 1)
• Channels: Dual channel for simultaneous measurement
• Sampling rate: 4 times per second
• Display: Backlit LCD
• Functions: T1-T2 differential, MAX/MIN/AVG, data hold, auto power off
• Power supply: 3 x 1.5V batteries
• Drop resistance: Up to 1 meter

How to use

To begin using the Uni-T UT320D, insert the provided batteries into the compartment on the back of the device. Connect the appropriate K or J type thermocouple probes to the input ports located at the top of the unit. Power on the device using the dedicated button and select your preferred temperature unit, Celsius or Fahrenheit. Place the probe tips in contact with the surfaces or substances you wish to measure. The LCD will display the real-time temperature readings for both channels. Use the function buttons to toggle between modes, such as viewing the temperature difference or locking the current reading on the screen.

What to consider before purchase

• Ensure your specific application requires contact-based measurement
• Verify that your existing probes are compatible with K or J type inputs if not using the included sensor
• Consider the environmental conditions to ensure they fall within the device's operational limits
• Check if the measurement range meets your specific industrial or laboratory requirements

Usage recommendations: Always ensure the thermocouple probe is securely connected to the device before taking measurements to avoid inaccurate readings. Clean the probe tips regularly to maintain optimal thermal conductivity and store the device in a dry, cool place when not in use to prolong its service life.
