Multimeter UNI-T UT181A

Product detailed description

Multimeter UNI-T UT181A
The UNI-T UT181A multimeter is an intelligent handheld multimeter with automatic or manual range switching that measures effective (RMS), maximum, minimum or average values. The instrument ranks in a higher class, excels in quality design and reliability and is also suitable for industrial use. The waterproof and dustproof rating is in the IP65 category. The display is a backlit graphic LCD type, with a maximum resolution of 4 5/6 digits, the maximum displayed value is ± 60000. The multimeter can measure AC/DC voltages and currents, resistance, diode test, continuity test, capacitance measurement, frequency, inverting, temperature, conductivity, comparative measurement, relative value measurement, peak detection and data logging up to 20000 data. The instrument allows data to be stored on a PC by connecting via USB adapter with optical decoupling, or via Bluetooth. The display includes an analogue display - bargraph with 61parts. The multimeter includes an internal clock that displays the time and date, which can be automatically assigned to stored samples of measured values at intervals of 1sec to 1h, including the time during which it should be stored (up to days). Possibility to include a low pass filter for measurements on inverters and generators. Possibility of dual-channel temperature measurement. Fusing of the current ranges is performed by tubular fuses (10A range by FF 10A H/1000V fuse (10 x 38mm); mA/µA range by FF 800mA H/600V fuse (6 x 32mm)). The instrument can test its own fuses (without opening the instrument). The power supply of the multimeter is made by a lithium battery 7,4V/2000mAh . Included in the package are measuring cables with spikes in safety category CAT III 1000V and CAT IV 600V.
