UNI-T UT181A True RMS Datalogging Multimeter with Bluetooth

UNI-T UT181A True RMS Datalogging Multimeter in Sri Lanka

Industrial-Grade Multimeter with Color Display and 20,000-Point Data Logging

The UNI-T UT181A True RMS Datalogging Multimeter is built for engineers and technicians who need more than a quick reading — it captures, stores, and trends measurement data over time. With a 1000V CAT III / 600V CAT IV safety rating, 10A current input, and a bright 3.5-inch color TFT display, it is designed for power distribution work, industrial equipment diagnostics, and extended monitoring tasks across Sri Lanka's electrical, HVAC, and manufacturing sectors.

Featuring onboard datalogging for up to 20,000 measurement points, trend-diagram plotting, dual temperature measurement, and dual connectivity via USB and Bluetooth, the UT181A lets technicians walk away from a test point and review long-term voltage or current behaviour later on a PC or mobile device. Its IP65-rated, double-molded housing is built to survive dusty panels, damp plant rooms, and everyday drops on site.
