Gr general radio 1432-m resis. decade box, calibrated
Just calibrated by our NIST-traceable lab, this is a used (but in excellent condition) GR decade box, the standard of the industry. Item is guaranteed to be within GR specifications, and a Certificate of Calibration is included, showing calibration date, standard(s) used, environmental conditions, etc.
Compare to new resistance boxes with similar specifications which cost over $2000.00.
Zero resistance is less than 0.01 ohm (see picture, in actuality less than 0.002 ohm). One ohm decade resistors are all within +/- 0.1% of nominal; all other decades are within +/- 0.02% of nominal, guaranteed. (As you can see from the pictures, readings are well within +/- 0.01% as measured on an HP 3457A.)
Minor dings and scratches here and there, but nothing that affects operation. Internally this unit is very clean and all switches work smoothly with good "feel." All resistors look new-no signs of overvoltage.
Only the General Radio 1432-M is included in this sale-other instruments are used only to show item's resistance readings.
As always you may call us at (***)-631-8353 for free consultation on this instrument or any other instrumentation requirements you may have.
