UNI-T True RMS UT18B MAX Digital Multimeter

Uni-T True RMS UT18B MAX Digital Multimeter
The Uni-T UT18B MAX is the most advanced model in this series, designed for users who need not only standard electrical measurements but also an additional LED testing function. The device measures DC and AC voltage up to 1000 V, DC and AC current up to 10 A, as well as temperature in the range from -55°C to 500°C. It maintains high precision and practicality, making it ideal for everyday use.


Practical features for service work
The model features a display with a maximum reading of 6000, as well as continuity test, Data Hold, relative mode, and adjustable backlight functions. Compared to other models in the series, it stands out with a dedicated LED diode test function, though it does not include a MAX/MIN mode. Automatic and manual range switching, auto-off, and intuitive operation ensure ease of use across various applications.


Expanded capabilities and full safety
The multimeter comes with a Type K thermocouple, allowing the user to immediately utilize the temperature measurement function. Safety is ensured by a wrong-wire connection alarm and CAT III 600V overvoltage protection. This model is designed for users who expect greater functionality and want a tool that is also useful for testing LED lighting.
