279301 for medium resistance from 0.1 to 1,111.210 Ħ in 1 mĦ steps (best suited for calibration of resistance thermometers or bridges
Features:
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 } 1.1mĦ at 0.1Ħ setting.
1 mĦ 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 dial system, various types of resistance thermometers and bridges can be calibrated accurately and promptly.
Excellent anti shock and -vibration properties
