1.0 DESCRIPTION

Introduction

The model HIn3550 is a compact, lightweight personal
magnetic field monitor employing three-axis detection,
enabling accurate measurement regardless of field
orientation. This instrument provides both instantaneous
and time integrated field measurements. A dual alarm
function (one for each measurement mode) is also
included.

Holaday Industries, Inc. introduced the model HIn3550
in response to demand from researchers and operators
working in the strong DC (static) magnetic fields
generated by medical diagnostic devices such as MRI's,
nuclear fusion experimental devices, metallurgical
processes or superconductive magnets. This monitor
measures the instantaneous and time integrated
exposures to such fields.

Thank you for selecting our model HIn3550 Magnetic
Field Monitor. Before using the instrument, please read
this manual thoroughly to obtain optimum test results and
keep it handy for reference.
