Description |
|
| The Model
421 is a benchtop, laboratory gaussmeter, capable of measuring magnetic
fields from 0.001 Gauss to 300 kGauss (measurement range is dependent
on probe used). This unit is well-suited to magnet testing, quality
assurance, and other applications requiring highly repeatable magnetic
measurements. Measurements of AC and DC magnetic fields are shown
in Gauss or Tesla on the two-line vacuum fluorescent display. A Sort
function allows magnet parts to be quickly checked on a pass/fail
basis, while the serial port enables the gaussmeter to be controlled
by a computer or automation equipment. A hall-effect gaussmeter probe
is included with the Model 421, and may be selected from an extensive
line of probe constructions. |
