DC resistance testers are core equipment in the field of electrical testing, widely used for measuring the DC resistance of power transformers, high-voltage switches, motor windings, instrument transformers, and other equipment. Market demand is expanding significantly as electrification accelerates across multiple industries.
In other industries, DC resistance testers have even broader applications, such as resistance testing of ultra-long cables in the wire and cable industry, contact resistance measurement of connectors in the battery industry, and resistance measurement of PCB traces and plated-through holes in electronics manufacturing.
The AT2515 DC Resistance Tester, developed by Onmeas Instruments as an upgraded successor to the AT515, provides comprehensive solutions for the industries mentioned above and other testing needs. Its ultra-wide measurement range can test ultra-low resistances such as wire resistance and solder joint resistance, as well as high resistance values up to 1.2GΩ. The built-in multi-level comparator enables manufacturers to use the comparison and sorting function for rapid production line deployment, efficient sorting, and ultra-high-speed testing that significantly reduces inspection time in production lines.
The AT2515 offers multiple interface functions and professional sorting capabilities, making it suitable for integration into automatic sorting systems for fully automated assembly line testing. It can be equipped with RS232/RS485/LAN/USB communication interfaces and USB drive interface, enabling convenient data communication and remote control with PCs.
