Uni-T UT320A Single Channel Contact Thermometer

The Uni-T UT320A is a compact, single-channel digital contact thermometer engineered for precise temperature monitoring in professional and technical environments. Designed to support K-type and J-type thermocouples, this device provides reliable performance across a broad temperature spectrum. Its robust construction and user-friendly interface make it an essential tool for technicians, engineers, and maintenance professionals who require accurate, real-time temperature data.

Advantages

This thermometer excels in versatility and ease of use, offering a wide measurement range that accommodates diverse industrial and laboratory needs. The inclusion of a high-contrast backlit display ensures clear visibility in various lighting conditions, while the ergonomic design allows for comfortable one-handed operation. With its fast sampling rate, the device captures temperature fluctuations efficiently, providing consistent and dependable results for critical diagnostics and process control tasks.

Suitable for

• HVAC system diagnostics and maintenance
• Industrial process temperature monitoring
• Laboratory research and testing
• Technical service and equipment inspection
• General temperature measurement in professional settings

This device may not be suitable for applications requiring non-contact infrared measurement, as it relies exclusively on physical contact via a thermocouple probe. It is also not intended for use in environments with extreme electromagnetic interference or hazardous atmospheres that require specialized explosion-proof equipment.

Key specifications

• Measurement range: -50°C to 1300°C (Type K) and -50°C to 1200°C (Type J)
• Accuracy: ±(0.5% + 1)
• Sampling rate: 4 times per second
• Display: Backlit LCD
• Functions: Data Hold, MAX/MIN/AVG modes, auto power off
• Drop resistance: Up to 1 meter
• Power supply: 3 x AAA batteries

How to use

To begin using the Uni-T UT320A, insert the provided batteries into the compartment on the back of the device. Connect the compatible K-type or J-type thermocouple probe to the input port located at the top of the unit. Power on the device using the dedicated button and select the appropriate probe type if necessary. Place the tip of the probe firmly against the surface or insert it into the medium you wish to measure. The current temperature will appear on the LCD screen. Use the Data Hold button to freeze the reading on the display for easier recording, or toggle through the MAX/MIN/AVG modes to analyze temperature trends over a specific period.

What to consider before purchase

• Ensure your application is compatible with K-type or J-type thermocouple probes.
• Verify that the temperature range of your target environment falls within the device's specified limits.
• Consider the need for additional specialized probes if your specific application requires unique contact methods.

For optimal accuracy, ensure the thermocouple probe tip maintains consistent, clean contact with the surface being measured. Regularly check the battery levels to prevent unexpected shutdowns during critical measurements and store the device in a dry environment when not in use.
