Project Description


HT3544 DC reistance meter
  • Offering 0.02% basic accuracy, 0.1μΩminimum resolution, 1A maximum test current
  • With measurable range 0.1μΩ~3.3MΩ.
  • Anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
  • Using the sorting indicator (option) with loud volume sound to accurately judge whether it is qualified or not at the production site.
  • Equipped with RS232/RS485/LAN interfaces and EXT I/O port, HT3544 multi-channel resistance meter is especially suitable for supporting ATE line to complete automatic test.
