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. |
