## Summary description

The Uni-T UT301D+ is a professional infrared thermometer designed for non-contact temperature measurement. It features high accuracy, a wide temperature range, and a clear display for industrial and maintenance applications. This reliable device allows for quick and safe thermal monitoring of surfaces, making it an essential tool for electrical, mechanical, and HVAC diagnostics in various professional environments.

## Long description

The Uni-T UT301D+ infrared thermometer is a professional-grade device engineered for precise non-contact temperature measurement. Designed for versatility and reliability, it operates within a broad temperature range from -32°C to 600°C. This instrument is an essential asset for professionals in electrical, mechanical, and HVAC sectors, providing rapid thermal data to ensure the safety and efficiency of various systems and equipment.
Advantages
This thermometer stands out due to its high repeatability and exceptionally fast response time of under 250 milliseconds, which allows for immediate identification of thermal anomalies. The inclusion of a dual laser system significantly improves targeting accuracy, ensuring that measurements are taken from the intended surface area. Furthermore, the adjustable emissivity feature, which includes five customizable presets, allows the user to calibrate the device for different materials, thereby increasing the reliability of readings across diverse industrial surfaces.
Suitable for
Electrical panel and circuit breaker diagnostics
HVAC system maintenance and airflow monitoring
Mechanical equipment and motor temperature checks
Industrial process monitoring and quality control
General facility maintenance and safety inspections
When it may not be suitable
This device is not intended for medical use, such as measuring human body temperature, as its accuracy specifications are optimized for industrial applications. Additionally, it may not provide precise readings on highly reflective or polished metal surfaces without proper surface preparation or the use of emissivity-correcting materials.
Key specifications
Temperature range: -32°C to 600°C
Response time: ≤250 ms
Distance to spot ratio: 12:1
Emissivity: 0.1–1.0 adjustable
Display: Color EBTN
Measurement modes: MAX, MIN, AVG, DIFF
Memory: Up to 99 data points
Power: 9V battery
How to use
To begin, power on the device and select the appropriate emissivity setting based on the material being measured. Point the dual laser at the target surface, ensuring the distance is appropriate for the 12:1 distance-to-spot ratio. Press the trigger to capture the temperature reading. You can utilize the HOLD function to freeze the measurement on the display or switch between MAX, MIN, AVG, and DIFF modes to analyze temperature variations over a specific period. The device will trigger visual and audible alarms if the temperature exceeds your pre-configured thresholds.
What to consider before purchase
Verify that the temperature range meets your specific industrial requirements.
Ensure the distance-to-spot ratio is suitable for the size of the objects you intend to measure.
Consider the material types you will be testing to ensure the adjustable emissivity feature covers your needs.
Check if the memory capacity for 99 readings is sufficient for your data logging requirements.
Usage recommendations
For the most accurate results, ensure the lens is clean and free of dust or debris. When measuring surfaces with low emissivity, such as shiny metals, consider applying a piece of matte electrical tape or specialized paint to the target area to improve measurement precision.
