UNI-T UT300A+ infrared thermometer

The UNI-T UT300A+ is a compact infrared thermometer designed for quick, non-contact measurement of surface temperature, especially on objects that are hard to reach or where direct touch is unsafe. It measures from -20 °C to 400 °C and is operated with a single button, with a response time of 500 ms. A 10:1 distance-to-spot ratio allows measurements from a somewhat greater distance, making it suitable for home, workshop and technical tasks.

The meter offers a repeatability of 1 °C or 1.0%, a fixed emissivity of 0.95 and a spectral response of 5.5 to 14 µm. A data hold function, backlit display, °C or °F unit selection and a laser pointer below 1 mW help you aim at the right measuring point. Automatic shut-off after 8 seconds and a low-battery indicator add to everyday convenience.

Weighing 146 g and measuring 135 × 94 × 36.5 mm, the thermometer is comfortable to hold and easy to carry. It operates between 0 °C and 50 °C at up to 90% relative humidity, without condensation. The package includes the thermometer, two 1.5 V LR03 batteries and a user manual.
