Leeds & northrup l&n 4755 resistance box, certified
The answer is, "Maybe they're really more expensive than we are."
Teletek: 100% guaranteed satisfaction. Period.
Just calibrated by our NIST-traceable lab, this is an L&N decade box, the standard of the industry. Item is guaranteed to be within L&N specifications, and a Certificate of Calibration is included, showing calibration date, standard(s) used, etc.
Zero resistance is less than 0.01 ohm. The 0.1 ohm decade resistors are within +/- 1% of nominal, the 1 ohm resistors are within +/- 0.25% of nominal, and all other decades are within +/- 0.02% of nominal.
Minor dings and scratches here and there, but nothing that affects operation. All switches work smoothly with good "feel." Internally this item looks good with no burned resistors (no sign of overvoltage applied).
As always, you may call us at (***)-631-8353 for free consultation regarding this instrument or any instrumentation needs you may have.
