Description
UNI-T UT181A Multimeter
The UNI-T UT181A is a smart portable multimeter with automatic or manual range switching that measures RMS, maximum, minimum or average values. The device belongs to a superior class, excels in quality design and reliability, and is suitable for industrial use. It is water and dust resistant, rated IP65. The display is a backlit graphic LCD with a maximum resolution of 4 5/6 digits, the maximum display value being ±60,000. The multimeter allows measurement of AC/DC voltages and currents, resistance, diode testing, continuity testing, capacitance, frequency, duty cycle, temperature, conductivity, comparative measurement, relative value measurement, data peak detection up to 02000 and data logging. The device allows data to be stored on a PC using an optically isolated USB adapter or Bluetooth. The display includes an analogue bar graph with 61 segments. The multimeter has an internal clock that displays the time and date, which can be automatically assigned to stored samples of measured values at intervals ranging from 1 second to 1 hour, including storage time (up to days). Option to include a low-pass filter for measurements on inverters and generators. Temperature measurement is possible on two channels. The fuses are protected by tubular fuses (10A FF 10A H / 1000V fuse (10 x 38mm); mA/µA FF 800mA H / 600V fuse (6 x 32mm)). The device can test its own fuses (without opening the device). The multimeter is powered by a 7.4V/2000mAh lithium battery. Test leads with CAT III 1000V and CAT IV 600V safety-rated tips are included.
