Product Description

 
TH0200 Standard Resistance Measuring Apparatus
TUNKIA TH0200 high precision accuracy 10 ppm Standard Resistor Measuring
1. Summary
The TH0200 is a high-precision, wide-range resistance measurement standard. It comes with a built-in reference resistor, enabling fast and accurate measurement of 0.01-grade or lower standard resistors/resistance boxes. It also supports external connection of a standard reference resistor for achieving even higher measurement precision.
This device utilizes a comparator bridge principle, making it ideal for metrology laboratories to perform measurement, comparison, transfer, and calibration of standard resistors or resistance boxes.
