UNI-T UT303C+ Infrared Thermometer This product comes with a 3-year warranty. The UT303C+ infrared thermometer can quickly and accurately determine surface temperatures between -32°C and +1300°C by measuring the infrared energy radiated from the target surface. For easier and more intuitive targeting of the device onto the target surface, a unique ring laser targeting indicator is incorporated, which is offered exclusively by Uni-Trend for its devices. The ratio of distance to the diameter of the measured surface is 30:1 with this instrument. It is possible to preset the emissivity of the measured surface within the range of 0.1 to 1.0 and to save the 5 most frequently used emissivities. Preset functions and measured values are displayed on a clear, high-contrast colour EBTN display, whilst limit values are indicated by red, green and blue LEDs on the top of the device and an audible alarm. You can set the system time and schedule repeated measurements in the future at a set interval, and save up to 99 measured values. The measurement time is also stored for each saved value. For these measurements, you will use the built-in standard socket for mounting on a tripod. The temperature measurement time is up to 250 ms in 95% of cases. It is possible to set minimum and maximum value limits, and measurements outside this range are indicated by an audible and visual signal. It is possible to display minimum, maximum and average temperatures, as well as deviations from the average (MIN, MAX, AVG, DIF).

UNI-T UT309A PRO Infrared Thermometer This product comes with a 3-year warranty. The UT309A professional non-contact infrared thermometer can quickly and accurately determine surface temperatures ranging from -35°C to +450°C by measuring the infrared energy radiated from the target surface. The UT309A is a highly durable device, suitable for everyday use. It is drop-resistant from 3m, and its excellent IP65 protection rating ensures good resistance to water and dust. The UT309A has a fixed emissivity of 0.95 and a targeting laser, which indicates the correct aiming of the thermometer. The distance-to-spot ratio is 10:1 with this instrument. The preset functions and measured temperature values are displayed on a high-contrast black-and-white LCD screen, whilst exceeding the temperature limits is indicated by LEDs (red for exceeding the upper limit and blue for the lower limit). It is possible to set a continuous measurement; after 2 minutes, the display backlight turns off, and once the measurement is complete by pressing the trigger button again, the temperature value remains on the display. The temperature measurement time is up to 250 ms in 95% of cases. It is possible to display the minimum, maximum and average temperatures, as well as the difference between the highest and lowest measured temperatures (MIN, MAX, AVG, DIF). The thermometer switches off automatically to reduce power consumption if not used for 8 seconds. This auto-off function can be disabled.
