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. This non-contact infrared thermometer can be used in a variety of fields, such as the food industry, vehicle maintenance, metalworking, cold storage and other industries.

This product comes with a 3-year warranty. The UTi730E thermal imaging camera is a top-of-the-range model operating in the infrared spectrum, designed to measure the surface temperature of objects within a range of -40°C to +400°C. The camera contains 76,800 uncooled vanadium oxide pixels, each with a 12μm vanadium dioxide sensor. The thermal image of objects, converted into a visible image using the selected colour palette, can be overlaid onto the image in the visible light range. A further 2 million pixels for visible light handle this. Setting the system date and time and generating QR codes for each photograph facilitates the subsequent classification of photographs. Manual or automatic triggering of the camera shutter at preset intervals. Saving images to the supplied microSD card or transferring them via Wi-Fi Hotspot, for example, to a laptop. Real-time image output via the USB-C connector to a laptop and TV. Switching temperature units between Celsius, Kelvin and Fahrenheit. Automatic monitoring of the hottest and coldest spots in the image with temperature indication, simultaneous temperature analysis of multiple objects: point, line, circular, rectangular. Setting temperature alarms. Image analysis on a PC or mobile phone using the supplied Vitta software and app. Removable 5200mAh Li-ion battery, which can be charged in the device or via an external charger. The UTi730E thermal imager will find wide application in the construction industry for detecting heat loss from masonry, roofs or pipes, in the energy sector for identifying electrical faults, in management, in cold stores, in service centres for locating overloaded equipment, and in scientific research.
