The UT677C Battery Internal Resistance Tester is microprocessor-controlled and features a built-in 16-bit ADC that accurately measures battery internal resistance and voltage. It is designed to perform measurements without interrupting the UPS system’s operation. By utilizing low-resistance AC measurement and noise-reduction technology, it allows for testing while the device under test remains in normal operation, significantly reducing test time. It also features data storage, bar graph display, data upload to computers, and Bluetooth connectivity with smart devices such as smartphones and tablets for wireless measurement and data retrieval. With a wide measurement range, high resolution, user-friendly operation, and portability, it offers accuracy, reliability, stable performance, and strong resistance to interference. It is an indispensable instrument for battery production, battery installation, equipment manufacturing, and equipment maintenance.

The UT258A AC/DC Clamp-On Leakage Current Meter is meticulously designed and manufactured for in-line measurement of DC and AC leakage currents and total currents up to 600 V. Utilizing the latest CT and digital integration technologies, its slim clamp design makes it particularly suitable for environments with dense wiring (such as power metering systems, high-speed rail systems, and automotive circuit maintenance). The non-contact measurement ensures operational safety. The meter is compact, highly accurate, stable in performance, and fully featured.

The UT117C is a handheld 60,000-count multimeter featuring high reliability and safety. Equipped with a high-resolution A/D converter and microcontroller-based data processing technology, this instrument features an LCD digital display, full-range overload protection, and a unique design, making it a superior-performing and safer electrical measurement instrument. This meter is characterized by its intelligence, high precision, high performance, and versatility. It can measure AC and DC voltage and current; AC voltage and current frequency; and offers low-pass filtering (LPF), as well as continuity, resistance, diode, and capacitance tests. It supports external current probes, NCV, and AUTO-VLOZ for automatic AC/DC voltage recognition. It is also equipped with wireless Bluetooth communication capabilities, allowing test results to be recorded and reported via the U-Lead Smart Test app. Application Areas: Installation and repair of household appliances; telecommunications maintenance; automotive troubleshooting; repair of electronic equipment; industrial engineering; scientific research and education; and maintenance of mechanical equipment.
