Extension Cables |
|
Each extension cable must be matched to a specific probe. To maintain probe accuracy, probes and extension cables for the Models 460, 450, and 421 must be calibrated together at Lake Shore. When ordering an extension cable (and more than one probe) it is necessary to specify with which probe the cable will be used. In addition, it should be noted that probes will exhibit their full accuracy specifications when used without an extension cable. Two- and three-axis probes for the Model 460 gaussmeter require two- and three-extension cables, respectively. Extension cables for the Model 475 and 455 are field programmable, but can be ordered factory calibrated. |

Hall Probe Stands |
|
|
These moveable probe stands consist of a 30 mm square post mounted on a 180 mm × 130 mm × 22.5 mm thick base plate. A probe holder is integrated into the stand. The holder can be moved up or down and fixed at any angle and location along the post. Two standard models are available. Consult Lake Shore for other post heights. |

Zero Gauss Chambers |
|
|
To obtain a null field reference a zero gauss chamber must be used to shield the probe sensing area from external field. The 4065 should be ordered with the Gamma Probe and can be used with the other probes.
