zł253.44
Tax included
The UT-139B is an advanced, universal digital multimeter designed for professionals and advanced electronics enthusiasts. The device is characterised by high measurement precision and a robust design, making it a reliable tool for daily service and laboratory work. The multimeter enables a wide range of measurements, including DC and AC voltage, current, resistance, capacitance, and frequency. Thanks to the automatic measurement range selection function, operating the device is extremely intuitive and fast, which saves valuable time during the diagnostics of electronic circuits.
One of the key advantages of the UT-139B model is the built-in VFC (Voltage Frequency Converter) filter, which effectively eliminates high-frequency interference during AC voltage measurements, ensuring high accuracy even in difficult working conditions. Additionally, the device is equipped with an NCV (Non-Contact Voltage) function, enabling non-contact detection of electric fields, which significantly increases user safety when working with electrical installations. The relative measurement mode (REL) and the data hold function are further features that facilitate precise data analysis. A large, clear, backlit LCD display guarantees excellent visibility of results even in poorly lit areas. A robust housing and a low battery alarm complete the package, making this multimeter an excellent choice for every technician.
