The UNI-T UT118B is a small but very practical digital multimeter, ideal for quick measurements in electrical equipment. Its slim design and intuitive handling make it a convenient tool for both professionals and those doing minor repairs at home.
The UT118B multimeter can measure direct current (DC) and alternating current (AC) voltages up to 300 V, which is sufficient for most basic service and installation tasks. With the ability to measure resistance up to 30 MΩ, you can easily check the condition of wires, fuses or soldered connections. Capacitance measurement down to 3mF also allows for a quick check of capacitors, which is sometimes useful for diagnosing power supplies or electronic circuits.
One of the main advantages of the UT118B is the Auto function, which automatically recognizes the parameter to be measured without having to manually change the range. This makes the device very easy to use and is ideal for quick measurements in tight spaces or when working with one hand. The multimeter is also equipped with a non-contact voltage detector (EF) function, which increases work safety.
The UT118B has an easy-to-read 28 x 14 mm LCD screen that makes it easy to read results even in low light conditions. The "data hold" function allows you to keep the readings on the screen, and the MAX/MIN modes allow you to monitor the values ​​in real time. In addition, the device automatically switches off after approx. after 10 minutes of inactivity to prevent unnecessary battery drain. The built-in low battery indicator reminds you when the battery needs to be replaced.
With a small size (20mm x 27mm x 182mm) and a weight of only 90g, the UT118B fits in a shirt pocket, tool bag or even a desk organizer. It works with a CR2032 battery, which is enough for many hours of use. Comes with basic accessories: battery and test cable - everything you need to get started right away.
