3-axis magnetic field meter

The TENMARS TM-192 measures extremely low frequency electromagnetic fields from 30Hz to 2000Hz using a triple-axis sensor. It provides readings in milligauss or microtesla across three automatic ranges. The 4-digit triple LCD shows simultaneous X, Y, and Z axis values. Data hold, maximum hold, and minimum hold functions capture key measurements.

Electricians and ELF survey technicians

Professionals assessing field intensity around power lines, transmission equipment, or appliances such as microwave ovens and monitors will find the meter suitable. It is not intended for buyers who require radio frequency or microwave band coverage. The single-axis resolution limits its use for users needing directional vector analysis beyond the displayed components.

30Hz to 2000Hz frequency response

This bandwidth defines the electromagnetic environments the instrument can characterise. Fields outside this range, including higher-frequency wireless signals, will not be measured accurately. The specified accuracy of ±(3.0%+30 digits) at 50Hz/60Hz applies within the stated response window.

Questions about this item

How often will the 9V NEDA 1604 battery need replacing during daily use?

The meter runs about 100 hours on one 9V NEDA 1604 cell, so a daily user swapping the battery every few weeks keeps it operating.

What measurement ceiling stops the TM-192 from reading stronger fields?

The highest range tops out at 2000 mG or 200 µT, and the display shows "OL" when the field exceeds that limit.

Does the triple-axis sensor or the LCD generate noticeable heat after hours of continuous logging?

The unit draws very little power and stays at ambient temperature; no active cooling is needed during extended sessions.
