Professional Digital Infra-Red Thermometer - UNI-T UT305C+

Description
The UT305C+ professional non-contact infrared thermometer can quickly and accurately determine surface temperatures from -50°C to +2200°C by measuring the infrared energy emitted by the target surface. For easier and more intuitive aiming of the device at the target surface, a built-in laser indicates the correct direction of the thermometer. The distance to diameter ratio of the measured surface is 55:1 for this device. This thermometer has additional built-in functions, such as measuring the temperature around the thermometer, measuring the temperature with a K-type contact thermocouple, and measuring the relative humidity around the thermometer. Based on these measured values, it automatically calculates the dew point temperature or wet bulb temperature. The system time and date can be entered into the thermometer. Measurement values can be programmed at predetermined intervals, and a total of 999 events (data groups) can be stored in the internal memory. The emissivity of the measured surface can be preset within a range of 0.1 to 1.0. The preset functions and measured values are displayed on a bright, high-contrast color TFT LCD display, and limit values are indicated by an audible signal and on the display. Minimum, maximum, and average temperatures can be displayed, as well as deviations from the average (MIN, MAX, AVG, DIF). The device is drop-resistant from a height of 1 meter.
This non-contact infrared thermometer can be used in a variety of industries, such as the food industry, machine maintenance, transportation equipment, metallurgy, cold storage, and other industries.
