Resistance tester series HT3544

The HT3544 precision DC resistance tester is one of the most precise 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 3 MΩ. Due to the minimum resolution of 0.1 μΩ and a measurement accuracy of 0.02%, the resistance tester is well suited for inspecting 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.




Main features of the HT3544 series

  • Tabletop device HT3544 with compact structure
  • Offers 0.02% measurement accuracy, 0.1μΩ minimum resolution, 1A maximum test current
  • Measurable range 0.1μΩ ~ 3.3MΩ.
  • The anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
  • Using the sorting display (option) with a loud volume, it can be precisely assessed whether it is qualified at the production site or not.
  • Anti-interference design suitable for complex use in electromagnetic field environments
  • Fast and high-precision testing, extensive interfaces
  • Equipped with RS232 / RS485 / LAN interfaces and EXT I / O port
  • Comprehensive interface configuration easy for system integration
