Precision, Safety, and Intelligence in One Tool
The Nexivoltra TSX-325 is a smart, autoranging digital multimeter built for professionals who demand accuracy without complexity. Whether you're troubleshooting a residential circuit, diagnosing an industrial motor drive, or testing components on a workbench, the TSX325 delivers laboratorygrade measurements in a rugged, pocketsized package.
Press the SMART button once and the TSX325 takes over. Its builtin AI instantly identifies what you're measuring voltage, resistance, capacitance, or continuity and automatically selects the correct range. No dial twisting. No range guessing. No blown fuses from wrong settings. For beginners, this means safety. For pros, this means speed. Switch to manual mode anytime with the same button when you need full control over range selection.
Under the hood, a highperformance True RMS engine paired with 6000count resolution delivers measurements you can stake your reputation on:
Every function calibrated for realworld precision, not just specsheet promises. For industrial environments with variable frequency drives, the dedicated VFC (Variable Frequency Control) mode measures inverter output voltages that standard meters simply cannot handle a feature typically found in meters costing two to three times more.
Safety isn't optional. The TSX325 features noncontact voltage (NCV) detection with a threecolor analog bar indicator and audible alarm. Hold the meter near any outlet, cable, or junction box and watch the bar light up green for low signal, yellow for medium, red for strong voltage all without making physical contact.
Need to identify a specific wire? Switch to LIVE mode, touch the red probe to a single conductor, and the meter instantly tells you whether it's hot or neutral, confirmed by both visual display and sound. Faster and more reliable than a standalone voltage pen.
The TSX325's vibrant color LCD screen presents readings in crisp, highcontrast digits with a dynamic analog bar at the top. The bright backlight ensures legibility in dark electrical panels, dim basements, and shaded junction boxes, while the antiglare display remains sharp and readable under direct sunlight.
When conditions get dark, activate the builtin flashlight to illuminate your workspace one less tool to carry, one less trip back to the toolbox. Data Hold freezes any measurement on screen, so you can record readings even when
