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.

Features

  • Desktop unit HT3544 with compact structure
  • Offers 0.02% measurement accuracy, 0.1μΩ minimum resolution, 1A maximum test current
  • Measurable range 0.1μΩ~3.3MΩ.
  • Anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
  • Sorting indicator (option) with loud volume can accurately judge whether it is qualified or not at the production site.
  • Anti-interference design, suitable for complex use in electromagnetic field environment
  • Fast and high-precision testing, extensive interfaces
  • Equipped with RS232/RS485/LAN interfaces and EXT I/O port
  • Extensive interface configuration easy for system integration
