TENMARS ELECTRONICS TM-195 3-Axis RF Field Strength Meter

RF field-strength meter

The Tenmars TM-195 is a digital RF field-strength meter that measures electric-field strength from 38 mV/m to 11 V/m across a 50 MHz to 3.5 GHz frequency span. Its triple-axis sensor captures isotropic readings without re-orientation, and a 4½-digit LCD shows values up to 19999 counts with resolutions down to 0.1 mV/m, 0.1 µA/m, 0.001 µW/m² and 0.001 µW/cm². Manual memory stores maximum and average readings, while configurable alarm thresholds and a clock support timed monitoring sessions.

RF engineers, installers and safety auditors

The meter suits RF engineers verifying transmitter output, wireless-network installers mapping Wi-Fi or cellular coverage, and safety auditors checking base-station power density or microwave-oven leakage. It also serves technicians hunting covert cameras or wireless bugs. Buyers who need logged data transfer, automated spectrum analysis or measurements below 50 MHz should look at other instruments.

50 MHz to 3.5 GHz frequency range

The single specification that decides fit is the 50 MHz to 3.5 GHz frequency range; signals outside this span cannot be measured. If the application involves lower-frequency magnetic fields, higher-frequency millimetre-wave links or real-time data streaming, a different analyser is required.
