Product Description TH0200 Standard Resistance Measuring Apparatus1. SummaryThe 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.References:JJG 166-2022 Verification Regulation of DC Standard Resistors.JJG 982-2022 Verification Regulation of DC Resistance Boxes.2.
