The professional UNI-T UT191T multimeter is a robust measuring instrument for everyday work in industry and service. It offers True RMS, measurement of AC/DC voltage and current up to 600 V/20 A, precise measurement of resistance, capacitance, frequency, and temperature, and an IP65 enclosure with drop resistance from 2 m. Thanks to the LoZ mode and both auto and manual ranging, it is reliable, safe, and ready for demanding applications.
The UNI-T UT191T is designed for accurate measurements in variable and demanding conditions. With True RMS technology, it reliably evaluates non-linear signals from inverters, UPS units, or variable frequency drives. The LoZ mode (low input impedance) minimizes the effect of ghost voltages and increases measurement confidence in industrial installations.
The durable construction with IP65 rating protects against dust and water, and the instrument withstands a drop from a height of 2 m. Practical features include auto/manual range, MAX/MIN functions, backlight, and a flashlight for work in dark areas. A clear 58 × 42 mm LCD with an analog bar graph makes readings easy.
Key advantages:
- Wide measurement range: AC/DC voltage and current, resistance up to 60 MΩ, capacitance up to 60 mF, frequency up to 1 MHz, temperature up to 400 °C.
- Safety and accuracy: True RMS, LoZ, ACV/ACA peak values, duty cycle 0.1–99.9%.
- Industrial durability: IP65, 2 m drop, stable field operation.
- User comfort: auto power-off, low battery indication, data hold, backlight and flashlight.
Package contents: multimeter, battery, pouch, temperature probe.
