True RMS measurement technology gives accurate results in AC current and voltage measurement regardless of waveform. This matters particularly on variable frequency drive (VFD) systems found in industrial settings, or where the sine wave is distorted. The CEM DT-3349W measures with high accuracy even under complex loads.
Bluetooth allows the CEM DT-3349W to work with the Meterbox iMM mobile app, so readings transfer to your device in real time and can be stored and analysed in the cloud. This simplifies data tracking during field work and speeds up reporting.
The instrument carries a CAT IV 600V / CAT III 1000V safety rating, meaning it is safe to use on high-energy circuits. A low pass filter prevents measurement errors on variable frequency drives, and the dual-injection plastic housing resists impact for long service life.
The large backlit LCD shows readings clearly, and several measurement parameters can be viewed at once — current, voltage, power factor, harmonic values and temperature are all easily followed on the same screen.
Harmonic distortion in power systems reduces equipment efficiency and power quality. The CEM DT-3349W analyses total harmonic distortion (THD) and individual harmonics to identify electrical distortion in the system, letting maintenance teams act early and improve energy efficiency.
The instrument powers off automatically after a period of inactivity, saving energy and extending battery life. A low-battery indicator warns the user in advance that a replacement is needed.
True RMS is the technology that measures accurately even on non-sinusoidal waveforms — critical for accurate energy measurement in industrial environments.
