2793 Decade Resistance Boxes 279301
High accuracy and stability
High reproducibility
Excellent reproducibility is obtainable because dial switches with low contact resistance are used. For example, changes in contact resistance is within 1.1mΩ at 0.1Ω setting.
1 mΩ resolution
Simple, quick dial operation
In-line display for city reading
Ideal for calibration of resistance thermometers and brides
Due to its high accuracy and a dail system, various types of resistance thermometers and bridges can te calibrated accurately and promptly.
