How to Select the Right Thermocouple Probe?

When choosing a thermocouple probe for your UNI-T UT320A/UT320D temperature tester, it is essential to consider the type of measurement you will be performing. There are two primary types of thermocouple probes available: K-type and J-type.

K-Type Thermocouple Probe

The K-type thermocouple probe is made of chromel-alumel alloys and is widely used due to its accuracy, stability, and wide temperature range. It is ideal for measuring temperatures in industrial environments, such as HVAC systems, automotive engines, and electronic components.

J-Type Thermocouple Probe

The J-type thermocouple probe is made of iron-constantan alloys and is commonly used for measuring temperatures in low-temperature applications, such as food processing and refrigeration systems. It has a narrower temperature range compared to the K-type probe, but it offers better accuracy in lower temperature ranges.

LCD Backlight & Temperature Measurement

The UNI-T UT320A/UT320D temperature tester features a large LCD display with backlight, allowing users to easily read temperature measurements even in low-light conditions. The display provides various options for displaying temperature readings, including Celsius, Fahrenheit, and Kelvin scales.

Display Options

• Celsius (°C)
• Fahrenheit (°F)
• Kelvin (K)

Measuring Techniques

To ensure accurate temperature measurements, it is crucial to follow proper measuring techniques. This includes ensuring the thermocouple probe is properly inserted into the measurement point, avoiding contact with other objects, and allowing sufficient time for the temperature to stabilize before taking a reading.

Mini Temperature Tester Usage Tips

To maintain the accuracy and longevity of your UNI-T UT320A/UT320D temperature tester, it is essential to follow proper calibration and maintenance procedures.

Calibration

Regular calibration is crucial to maintain the accuracy of your temperature tester. It is recommended to calibrate the device at least once a year or as needed, depending on the frequency of use and environmental conditions.

Maintenance

Proper maintenance is essential to ensure the longevity of your temperature tester. This includes cleaning the device regularly, storing it in a cool and dry place, and avoiding exposure to extreme temperatures or humidity.
