The Uni-T UT300S is a compact infrared thermometer designed for quick and convenient surface temperature measurement. The device operates in the range from -32°C to 400°C, offers simple one-button operation, and is ideal for measuring objects that are difficult to access or dangerous to touch directly. With a 12:1 distance-to-spot ratio, it allows for convenient temperature measurement from a greater distance.
The UT300S model features a response time of 500 ms, an accuracy of ±2°C or ±2%, and a repeatability of ±0.5°C or ±0.5%. Adjustable emissivity in the range of 0.10–1.00 allows for better adaptation to various surfaces, and the laser sight makes it easier to precisely indicate the measurement location. Additionally, the device features Data Hold, a backlit display, and the option to select units in °C or °F.
The device is powered by a 9V 6F22 battery, weighs 185 g, and measures 153 × 108 × 40 mm, making it fit comfortably in the hand and easy to carry. Automatic shut-off after 8 seconds helps save energy, and the low-battery indicator makes it easy to check readiness for use. It is a practical tool for daily surface temperature measurements at home, in the workshop, and for technical work.
