The UNI-T UT301D+ is a professional non-contact infrared thermometer designed for fast, safe and reliable surface temperature measurement from -32°C to 600°C. With a 12:1 distance-to-spot ratio, adjustable emissivity, rapid ≤250ms response time, high/low temperature alarms and 99-group data storage, it is ideal for maintenance, electrical inspection, HVAC, industrial applications and general temperature monitoring.
Turn on the thermometer and select the required temperature unit, °C or °F.
Point the infrared sensor toward the surface you want to measure while maintaining a suitable distance.
Activate the measurement and read the temperature on the color EBTN display.
Use MAX, MIN, AVG or DIFF modes and store measurements for later reference when required.
The UNI-T UT301D+ is designed to measure the temperature of surfaces without physical contact. Infrared technology allows users to check hot, cold or difficult-to-reach areas quickly while maintaining a safe distance.
It is particularly useful for identifying abnormal temperature conditions in electrical equipment, machinery, HVAC systems, motors, bearings, pipes, panels, industrial equipment and other surfaces where contact measurement may be inconvenient or unsafe.
The UT301D+ combines wide temperature coverage, fast response, adjustable emissivity and advanced alarm functions in a compact handheld instrument.
Its 12:1 D:S ratio makes it suitable for checking temperature from a reasonable distance, while MAX/MIN/AVG/DIFF modes and 99-group storage provide additional flexibility for professional inspection and maintenance work.
For checking electrical panels, connections, breakers and components for abnormal heat.
For checking pipes, ducts, air-conditioning components and temperature differences.
Useful for preventive maintenance and identifying overheating equipment.
Suitable for machinery, motors, bearings and industrial process inspections.
The UT301D+ can be used across a wide range of professional and maintenance environments, including:
≤250ms response time supports quick inspections.
Non-contact measurement helps inspect hot or difficult-to-reach surfaces.
Adjustable emissivity and multiple measurement modes improve application flexibility.
99-group data storage supports recording and reviewing measurements.
The UNI-T UT301D+ measures temperatures from -32°C to 600°C (-25.6°F to 1112°F).
Yes. It uses infrared technology to measure surface temperature without physically touching the target.
The 12:1 distance-to-spot ratio means the thermometer can measure a relatively smaller target area from a greater distance compared with a lower-ratio infrared thermometer.
Yes. Emissivity can be adjusted from 0.1 to 1.0, and the thermometer can store five preset emissivity values.
Yes. It provides both high/low temperature LED and audible alarms.
The thermometer supports storage of up to 99 groups of measurement data.
The UT301D+ provides MAX, MIN, AVG and DIFF measurement modes, along with data hold and lock measurement functions.
The UNI-T UT301D+ operates using a 9V battery.
Yes. The UT301D+ features a tripod mounting hole for applications requiring stable positioning.
It is suitable for electricians, HVAC technicians, industrial maintenance teams, automotive technicians, engineers, workshops and general equipment inspection.
