Product information

Description

The UNI-T UT309C is a professional-grade infrared thermometer engineered for precise non-contact temperature measurement by detecting infrared energy radiated from a target surface. This robust device is built to withstand harsh industrial conditions, featuring an IP65 dust and water resistance rating and a 3-meter drop-proof design. With a rapid response time of 250ms and dual laser targeting, it provides reliable and efficient data for engineers and maintenance professionals.

Advantages

This thermometer offers exceptional durability and performance in demanding environments. Its high-precision sensors ensure accurate readings across a wide temperature range, while the adjustable emissivity allows for versatility when measuring different types of materials. The inclusion of dual lasers improves targeting accuracy, and the device is equipped with advanced features such as MAX, MIN, AVG, and DIF modes to assist in comprehensive thermal analysis. The large, backlit LED display ensures clear visibility in low-light conditions, and the high/low temperature alarms provide immediate visual feedback for safety and process control.

Suitable for

  • Electrical distribution system inspections
  • HVAC system maintenance and diagnostics
  • Transportation equipment monitoring
  • Industrial machinery and instrument repair
  • General surface temperature monitoring in manufacturing

This device may not be suitable for measuring the internal temperature of objects, as it is strictly designed for surface temperature detection. It is also not intended for medical use or for measuring body temperature.

Key specifications

  • Temperature range: -35°C to 650°C
  • Distance-to-spot ratio: 12:1
  • Response time: 250ms
  • Emissivity: Adjustable from 0.1 to 1.0
  • Dual laser targeting system
  • IP65 protection rating
  • 3-meter drop resistance
  • Power source: 9V battery

To use the thermometer, point the device toward the target surface and pull the trigger to initiate the measurement. The dual lasers will help you define the measurement area. The device will display the temperature on the screen instantly. You can toggle between Celsius and Fahrenheit, adjust emissivity settings for specific materials, or use the lock measurement feature for continuous monitoring during long-term inspections.

What to consider before purchase

  • Verify that the 12:1 distance-to-spot ratio is sufficient for your specific measurement distance.
  • Ensure the adjustable emissivity range meets the requirements of the materials you intend to measure.
  • Confirm that the temperature range of -35°C to 650°C covers your operational needs.
For the most accurate results, ensure the target surface is clean and free of obstructions. When measuring reflective surfaces, adjust the emissivity setting accordingly to compensate for surface properties.
