Introduction of TUNKIA Resistance Standards Series

Today, we are excited to introduce TUNKIA’s Resistance Standards Series—a comprehensive portfolio covering three major categories: resistance measurement instruments, standard resistors, and analog standard resistors. Whether you're a resistor manufacturer or a metrology engineer seeking ultra-precise measurements across a wide resistance range, this article will provide valuable insight into our solutions.

First of all, let's clarify the definitions of these three categories of products.

1. What is a Resistance Measurement Instrument?
A resistance measurement instrument is a specialized device used to measure resistance values. It is suitable for measuring, comparing, transferring, and calibrating standard resistors, precision resistors, and other resistance components. It is widely used in metrology and calibration labs, quality control, and R&D. Most of these instruments are based on comparator bridge principles.

2. What is a Standard Resistor?
A standard resistor is a resistor with a stable and traceable resistance value, certified by metrology institutions. It serves as a resistance reference for calibration, comparison, and unit transfer.

3. What is a Analog Standard Resistor?
A simulated standard resistor is a device constructed using adjustable circuits or electronic components that can simulate different resistance values. It is used to replace physical standard resistors across various ranges for simulated calibration, comparison, or functional testing.

After understanding the basic definitions of these three types of resistance standard instruments, you may be more concerned about: What specific models does Tunkia provide? What application scenarios are they suitable for? What technical advantages do they have? Why not continue to learn more about them one by one?

To meet diverse needs from ultra-low to ultra-high resistance measurement and calibration, TUNKIA offers a selection of products across all three categories:
