Got questions, ask an expert!
The UNI-T UT181A is a 60,000-count True RMS digital multimeter with trend capture and storage for up to 20,000 measurement records. Its colour display, high accuracy, dual-temperature inputs and low-pass filter support advanced electrical diagnostics and long-term monitoring.
Key Features
- 60,000-count True RMS measurement with 0.025% basic DC voltage accuracy and up to 100kHz AC bandwidth.
- Stores up to 20,000 measurement records and displays captured data as trend graphs for long-term monitoring and fault analysis.
- 3.5-inch 64K colour TFT display provides clear presentation of measurement values, trends, date and time.
- Dual-temperature inputs display T1, T2 and differential temperature values for comparative monitoring.
- 1kHz low-pass filter supports measurements on variable-frequency drives and motor-control equipment, while USB connectivity enables PC data transfer.
