Hioki RM3545A-2 Resistance Meter

The Hioki RM3545A-2 Resistance Meter is a sophisticated instrument designed for highly accurate resistance measurements, making it ideal for various applications in both development and production environments. This model is equipped with advanced features such as a temperature measurement function that works with a high degree of precision when using the Temperature Sensor Z2001, and it can also accept analog input from a radiation thermometer.

A standout feature of the RM3545A-2 is its capability for multi-channel measurements, made possible by the optional Z3003 Multiplexer Units, allowing it to measure up to 20 channels using the 4-terminal method. With the addition of the Switch Mainframe SW1002, it can accommodate up to 132 channels, responding to the market demand for low-cost and space-saving solutions​.

Hioki RM3545A-2 Key Features

  • 0.045% basic accuracy, 1 nΩ max. resolution, 1A max. testing current
  • Measure from 1 nΩ (testing current 1 A) to 1200 MΩ
  • Equipped with advanced features, ensuring precise resistance measurement (OVC, temperature measurement, and correction function)
  • The RM3545A-2 can be equipped with up to two optional Z3003 Multiplexer Units, allowing it to measure up to 20 channels (using the 4-terminal method)
  • High path resistance tolerance allows seamless integration into an automatic test system, eliminating concerns about wiring or contact resistance
