GETTING STARTED
1- Introduction
Metrolab’s Three-axis Magnetometers are used to measure magnetic field
strength. Simultaneous measurement of all three components of the magnetic
field provides the total field no matter the orientation of the probe, which greatly
facilitates many measurement tasks such as field mapping. The extraordinarily
compact design, along with the optional ruggedized tablet, makes for a powerful,
autonomous and portable magnetometer, excellent for field use.
This manual covers the entire THM1176 family, including the following models:
A. THM1176-MF (“Three-axis Hall Magnetometer –Medium Field”),
B. THM1176-HF (“Three-axis Hall Magnetometer –High Field”),
C. THM1176-HFC (“Three-axis Hall Magnetometer –High Field Compact”),
D. THM1176-LF (“Three-axis Hall Magnetometer –Low Field”), and
E. TFM1186 (“Three-axis Fluxgate Magnetometer”).
For an overview of the capabilities of each of these instruments, please see
Chapter 3-Overview, Chapter 6-Technical Specifications and Chapter 7-
