Uni-T UT301A+ Infrared Thermometer
The Uni-T UT301A+ is a rugged and user-friendly infrared thermometer designed for quickly detecting temperature anomalies in everyday technical work. The device measures temperatures ranging from -32°C to 420°C, offers an accuracy of ±1.5°C, and has a response time of up to 250 ms, allowing for efficient monitoring of equipment and installation surfaces without contact with the object being tested. Thanks to a D:S ratio of 12:1, adjustable emissivity of 0.1–1.0, and a color EBTN display, this model performs well during inspections of electrical installations, HVAC equipment, vehicle diagnostics, and other maintenance tasks.
Precise temperature control and convenient alarms
The UT301A+ model features adjustable emissivity with the ability to save 5 sets of settings, making it easier to adapt measurement parameters to different surfaces and increasing reading accuracy. The device offers audible and visual alarms for high and low temperatures, a measurement lock function, and MAX, MIN, AVG, DIFF, and Hold modes, which help analyze results more effectively. An additional advantage is the tripod mounting hole, which enhances convenience during extended temperature monitoring.
Compact design for everyday use
The thermometer is powered by a 9V battery and features a 30 × 30 mm display, ensuring clear data readability. With dimensions of 160 × 74 × 48 mm, a weight of 204 g, and the ability to withstand a 1-meter drop, the device is well-suited for field and service work. The model can operate at temperatures ranging from 0°C to 50°C and humidity below 90% RH without condensation, which enhances its practicality in various conditions.
