Hộp điện trở chuẩn Yokogawa 2792A, 2793 # 279303, 2793 # 279301
Model 2793 resistance box is high-accuracy, stable DC variable resistor with 6 dials and is available in two styles: 279301 for medium resistance from 0.1 to 1,111.210 Ω in 1 mΩ steps (best suited for calibration of resistance thermometers or bridges); 279303 for high resistance from 0 to 111.1110 MΩ in 100 Ω steps (suitable for calibration of insulation resistance testers or bridges).
- 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 dial system, various types of resistance thermometers and bridges can be calibrated accurately and promptly.
- Excellent anti shock and -vibration properties
