UNI-T UT267B Intelligent 3 Phase Voltammeter
The UNI-T UT267B Intelligent 3 Phase Voltammeter is a modern, digital measuring instrument specifically designed for the efficient and safe analysis of three-phase electrical systems. Built with robust materials and insulated protection, it ensures safety and durability during field use. This meter allows for direct measurement without the need to disconnect the power, making it ideal for real-time diagnostics. With its ability to measure voltage, current, frequency, and phase angles, the UT267B supports comprehensive monitoring of electrical parameters in complex systems. The UNI-T UT267B also calculates active, reactive, and apparent power, as well as the power factor and current vector sum, offering a complete overview of energy flow and system behavior.
Its user-friendly LCD display presents readings clearly, along with vector diagrams that visualize phase relationships. Data storage capability and RS232 interface enable users to log, review, and analyze up to 500 sets of data on a computer for reporting and further evaluation. The meter is commonly used in power distribution checks, relay protection systems, transformer monitoring, and wiring validation tasks. Thanks to its compact design, intuitive interface, and reliable performance.
The UNI-T UT267B is widely adopted by electricians, maintenance engineers, and power utility technicians for routine inspection and troubleshooting in industrial and commercial environments.
