This product comes with a 3-year warranty. The UT305S professional non-contact infrared thermometer can quickly and accurately determine surface temperatures between -50 °C and +2000 °C by measuring the infrared energy radiated by the target surface. To make aiming the device at the target surface easier and more intuitive, a ring laser is built in, which indicates the correct alignment of the thermometer. The ratio of distance to the diameter of the measured surface is 50:1 with this instrument. This thermometer is drop-resistant from a height of 1 metre. It is possible to preset the emissivity of the measured surface within the range of 0.1 to 1.0. The display of preset functions and measured values is provided by a clear, high-contrast colour EBTN display, whilst limit values are indicated by an audible alarm and on the display. It is possible to display minimum, maximum and average temperatures, as well as deviations from the average (MIN, MAX, AVG, DIF). The thermometer switches off automatically to reduce power consumption if left unused for 15 seconds in HOLD mode and 10 seconds in other modes. The temperature measurement time is up to 250 ms in 95% of cases.

UNI-T UT171C Multimeter The UT171 series multimeters are portable multimeters with automatic and manual range switching and a resolution of 4 3/4 to 4 5/6 digits. These devices belong to the upper mid-range class, excel in quality design and reliability, and are also suitable for industrial use. They can measure AC/DC voltage and current, resistance, diode test, continuity test, capacitance, frequency, duty cycle, temperature, 4-20mA current loop, conductivity, VFC, and NCV. The devices allow data storage and connection via USB with optical isolation or via Bluetooth. The UNI-T UT171C multimeter is the best instrument in the UT171 series. Unlike the UT171A, the UT171C has a wider range for resistance and capacitance measurement, as well as (reverse) resistance measurement. The display type is OLED with a dot matrix. The display range is ±60,000 for voltages, currents and frequencies, and ±6,000 for capacitance measurements. The display includes a 31-segment analogue bar graph. The refresh rate is 4 to 5 times per second. The fuses are protected by tubular fuses (10A FF 10A H / 1000V fuse (10 x 38mm); mA / µA FF 800mA H / 600V fuse (6 x 32mm)). The device can test its own fuses (without opening the device). The multimeter is powered by a 7.4 V / 1800 mAh lithium battery. The measurement range can be selected automatically or manually.
