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.
