Our high - tech company, with over 14 years of industry experience since its inception in 2011, offers a commercial electric voltage tester that meets the demanding requirements of commercial electrical systems. This tester is specifically designed for use in large - scale commercial buildings, industrial facilities, and electrical contractors' projects. It features a rugged and durable construction, made from high - strength materials that can withstand the rigors of daily use in harsh commercial environments. The commercial electric voltage tester is equipped with advanced voltage measurement technology, capable of accurately measuring both AC and DC voltages over a wide range, typically from 0 to 1000V for AC and 0 to 1500V for DC, with an accuracy of ±0.3% of the reading. The device has a large, industrial - grade display that provides clear and easy - to - read voltage readings, even from a distance. To ensure safety in commercial settings, it is loaded with multiple safety features, such as insulated probes, high - voltage protection circuits, and a built - in grounding check function. The commercial electric voltage tester also offers enhanced functionality, including phase sequence detection, harmonic analysis, and data logging capabilities, which are essential for maintaining and troubleshooting complex commercial electrical systems. It supports various communication interfaces, such as USB and Ethernet, allowing for easy transfer of measurement data to a computer for further analysis. With its compliance with international standards and certifications like CE, UL, and CSA, our commercial electric voltage tester is a trusted and reliable tool for professionals working in the commercial electrical industry.
