It logs readings, captures trend graphs on its own display, and pairs to a Bluetooth app — so an intermittent fault or a slow drift you'd miss with spot readings shows up as a curve. It's rated CAT III 1000 V \/ CAT IV 600 V.\u003c\/p\u003e\n\u003cp\u003eMeasurement covers AC\/DC voltage and current to 1000 V and 10 A, combined AC+DC, resistance to 60 MΩ, capacitance to 60 mF, frequency, temperature to 1000 ℃, plus a low-pass filter, dBV\/dBm, conductance, duty cycle, and peak hold. A 1 m drop rating keeps it field-ready. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product-container\"\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e60,000-count True-RMS measurement\u003c\/li\u003e\n\u003cli\u003eOn-board data logging with trend-graph capture\u003c\/li\u003e\n\u003cli\u003eBluetooth app for live readout and transfer\u003c\/li\u003e\n\u003cli\u003eAC+DC combined measurement; AC\/DC to 1000 V and 10 A\u003c\/li\u003e\n\u003cli\u003eResistance to 60 MΩ, capacitance to 60 mF, frequency, temperature to 1000 ℃\u003c\/li\u003e\n\u003cli\u003eLow-pass filter for drive output; dBV\/dBm; conductance; duty cycle\u003c\/li\u003e\n\u003cli\u003eRelative, max\/min, peak hold, and data-comparison modes\u003c\/li\u003e\n\u003cli\u003eUSB interface; CAT III 1000 V \/ CAT IV 600 V; 1 m drop\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product-container\"\u003e\n\u003ch2\u003eUT181A Details\u003c\/h2\u003e\n\u003ch3\u003eLogging \u0026amp; Trend Capture\u003c\/h3\u003e\n\u003cp\u003eThe UT181A records readings over time and plots them as a trend on its own graphing display, so intermittent faults and slow drift become visible patterns instead of numbers you have to watch.
