DECADE RESISTANCE BOX, PL 34 |
Decade Resistance Box consists of decade switches with precision resistors. Each decade switch has 1-10 position in addition to zero position. The decades are housed in metallic rugged casing and provided with knobs having ribs for comfortable operation. An extra terminal is provided with a series fuse for protection. Decade Resistance Boxes are available with 4,5,6,7 & 8 decades and offer a wide choice of resistance to meet with requirements in industry and laboratories.
- Wide choice of models
- (0.1 ohm to 1 Meg ohms)
- Precision resistors
- Low temperature co-efficient
- 4,5,6,7 & 8 decade models
- Low contact resistance switches
- Sturdy, rugged construction
- Fuse protected
