Description
The HT3544 Precision DC Resistance Tester is one of the most accurate DC resistance testers in the industry. The HT3544 DC resistance tester has a 3.5 inch display and has a measuring range of 3mΩ to 3MΩ. Due to the minimum resolution of 0.1 μΩ and a measurement accuracy of 0.02%, the resistance tester is well suited for inspection of converter motors and other applications that require high-resolution resistance measurement. Equipped with RS232/RS485/LAN interfaces and EXT I/O port, the devices of the HT3544 resistance tester series are suitable for performing automatic tests in test or production lines.
