Digital Multimeter UNI-T UT18B Max
Overview
Description
The UNI-T UT18B MAX is a reliable digital True RMS multimeter with a 6000-count display, EMI anti-interference protection, quick response, and a handy design. The meter incorporates two major new features: a misoperation alarm and an any-button wake-up. A built-in VFD feature filters out interference from the carrier frequency overlapped by the sine wave or voltage signal distortions and may measure the output voltage of variable frequency drive. In DC/AC mode, the multimeter can also handle frequency and duty cycle measurements.
The UNI-T UT18B MAX comes with a two-pair set of standard gold-plated test leads and gold-plated fine-tipped test leads, while the 1000V full-range input overvoltage protection makes it a secure choice for engineers and electrical technicians.
Features
- Measurement functions:
- DC/AC voltage;
- DC/AC current;
- resistance;
- capacitance;
- frequency;
- temperature;
- duty cycle;
- diode testing;

- True RMS measurements
- Fast measurement times
- The VFD feature providing for accurate, interference-free voltage measurements by applying a low-pass filter to AC voltages under test
- Enhanced safety thanks to a full-range 1000V input overload protection
- Robust EMC anti-interference protection
- Misoperation alarm at the current measurement function: the multimeter sounds an audible alert and displays a visual warning whenever the rotary switch is set incorrectly or the test lead is connected to the incorrect input terminal
- Instant any-key wake-up feature
- Sturdy built and compact design
