The UNI-T UT191E is a professional digital multimeter designed for use in harsh industrial environments. Equipped with the True RMS function, the meter provides accurate voltage, current, resistance, capacitance and frequency measurements. The UT191E offers 6000 resolution and automatic or manual range selection. The housing of the meter complies with the IP65 standard and can withstand being dropped from a height of up to 2 meters, making it an ideal device for use in harsh and changing environments.
The UT191E multimeter is capable of measuring DC and AC voltages up to 600 V and DC and AC currents up to 20 A, making it suitable for a wide range of applications in industry, service or installation. The measurement accuracy is ±(0.5% + 3) for direct voltage, ±(0.7% + 3) for alternating voltage. In addition, the meter can measure resistance up to 60 MΩ, capacitance up to 60 mF and frequency up to 1 MHz. The operating time measurement covers the range between 0.1% and 99.9%, so the analysis of pulse signals becomes simple.
Thanks to True RMS technology, the multimeter accurately measures the value of signals with irregular waveforms, which is essential for inverters, UPS, etc. for measurements of systems powered by The LoZ (low input impedance) mode increases the reliability of measurements in industrial facilities.
The housing of the measuring instrument complies with the IP65 standard, which means complete resistance to dust and water. In addition, the device also passed a drop test from a height of 2 meters, making it extremely durable even in construction and industrial conditions.
