TH0200 Standard Resistance Measuring Device
The TH0200 is a high-precision and wide-range resistance measurement standard designed for calibration laboratories, metrology centers, and research institutions. Equipped with a built-in reference resistor, it allows fast, stable, and highly accurate measurement of 0.01-grade or lower standard resistors and resistance boxes. Its advanced architecture ensures low noise, high resolution, and excellent measurement repeatability across all supported resistance ranges.
