Level Measurement & Control


Handheld gaussmeters

March 2000 Level Measurement & Control

A new series of FW Bell portable Hall-effect gaussmeters is available from PREI Instrumentation. The inexpensive basic model measures DC fields up to 25 kG with an accuracy of 4% while the top model measures DC and true RMS AC fields up to 30 kG with an accuracy of 1%.

All models are battery operated, have a detachable transverse probe, a 3,5-digit LCD and read in Gauss or Tesla. The instrument functions include auto zero, max/min hold, peak hold and auto range. The top model also has an analog output and an RS232 communications port. User prompts on the LCD allow fast, simple pushbutton operation. Axial and other style probes are available as options.

These 5000 Series gaussmeters are suitable for use in both sensitive laboratory environments and rugged industrial settings.
