UNI-T UT309E PRO Infrared Thermometer The UT309E professional non-contact infrared thermometer can quickly and accurately determine surface temperatures ranging from -35 °C to +850 °C by measuring the infrared energy radiated by the target surface. For easier and more intuitive targeting of the device onto the target surface, a dual-wavelength rotating laser is built in, which indicates correct targeting of the thermometer. The distance-to-spot ratio is 20:1 with this instrument. This thermometer also features IP65 protection against water and dust and can withstand a drop of up to 3 metres. 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 EBTN colour display, whilst limit values are indicated by LEDs. You can set the system time and schedule repeated measurements in the future with a maximum interval of up to 96 hours between two measurements, and store up to 99 measured values in memory. The measurement time is also stored for each stored 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). The thermometer switches off automatically to reduce power consumption if not used for 8 seconds. This automatic switch-off can be disabled.

UNI-T UT204R Clamp Multimeter This product comes with a 3-year warranty. The UT204R digital clamp meter is used to measure AC and DC voltages up to 600V, AC and DC currents up to 600A, and frequencies from 10Hz to 60kHz up to 1600V for low voltage. 10MHz for low voltage. It features protection against voltages exceeding 600V across all ranges, as well as an audible and visual alarm. Four-digit multi-segment display measuring 37 x 25 mm with backlighting and fast refresh rate (3 times/s). The jaw opening allows measurement on cables with a diameter of up to 28 mm.

This product comes with a 3-year warranty. The UTi722M thermal camera is a professional camera for smartphones (Android) that operates in the infrared spectrum, designed to measure the surface temperature of objects in the range from -20 °C to 450 °C. The camera is designed to be connected to a standard smartphone, preferably one equipped with a USB-C port. However, it is possible to connect the camera to the phone using an extension cable. On your mobile phone screen, you can view the thermal image of objects, converted into a visible image using the selected colour palette: iron red, rainbow, greyscale, hot red, black and white, lava, high-contrast rainbow. In real time, you can have the minimum and maximum temperature locations marked on the image with data in degrees Celsius or Fahrenheit. Option to set alarms when a certain temperature is exceeded. The image from this camera can be picture-in-picture (PIP) with the image from the front or rear camera of the mobile phone, whilst the infrared image can be mirrored at the same time. It is possible to analyse the temperature at a marked point or area (rectangle, circle, line, etc.) of the object being measured. Trigger the camera shutter automatically or manually, and save photos or videos. Ability to edit photos within the app. Advantages of thermal imaging: 1. Intuitive, efficient and convenient, allowing users to directly ‘see’ temperature fluctuations in the measured object 2. The thermal status of different locations for a comprehensive analysis, providing more information to assess fault locations.

This product comes with a 3-year warranty. The UNI-T UT25CL cable locator is a powerful device comprising a transmitter and a receiver. Featuring state-of-the-art sensors, it effortlessly tracks cables and wires, saving time and preventing accidental damage during installations or repairs. This tool detects wires, identifies breaks or short circuits, traces underground cables and locates fuses and related equipment. It also detects short circuits and open circuits in underfloor heating, monitors metal water and heating pipes, and supports up to 8 transmitters. It is ideal for residential or commercial projects. The UT25CL handheld detector can be used to trace the route of low-voltage cables buried in the ground (e.g. cables in walls); to test and diagnose disconnections, short circuits and other problems occurring on cables; and to determine whether the cable being tested is live. The transmitter can display the corresponding voltage (power cable voltage: ≥8V), whilst the receiver can simultaneously display signal strength, transmitter code, transmitter power level, low battery, etc. The UT25CL has many advantages, including accurate measurement, easy operation, a clear display and much more.

This product comes with a 3-year warranty. The UT331+ and UT332+ measuring instruments measure temperature and humidity with high precision; they determine the dew point temperature and wet-bulb temperature. They allow you to set the system time and date and to store the measured data in memory, either manually or automatically at set intervals. The measured data can subsequently be exported to computer software for further analysis. These meters can be used in factories, the food industry, healthcare, laboratories, environmental protection and other fields. The devices contain a high-precision sensor and a low-power microprocessor; 4 x 1.5V AAA alkaline batteries are sufficient for power supply. The UT332+ differs from the UT331+ in terms of higher accuracy and greater data storage capacity.
