UNI-T UT210E digitale stroomtang True RMS 2000 counts AC/DC stroom spanning weerstand capaciteit frequentie NCV auto range

Electricians and HVAC technicians rely on the UNI-T UT210E for quick, non-invasive current measurements in tight breaker panels and crowded junction boxes. Its compact clamp jaw opens to 17 mm, letting you measure AC/DC current up to 100 A without breaking the circuit. The meter's True RMS capability ensures accurate readings even on distorted waveforms from variable frequency drives or electronic ballasts.

Why choose it

The UT210E combines True RMS accuracy with a slim, ergonomic design that fits comfortably in one hand. Auto ranging eliminates manual range selection, while the bright backlight and data hold make it easy to capture readings in dimly lit panels. Non-contact voltage detection adds an extra layer of safety before you start work.

Ideal use cases

• Measuring motor inrush current without disconnecting wires
• Verifying AC/DC loads in residential and commercial panels
• Troubleshooting HVAC compressors and fan motors
• Testing capacitors and diodes on circuit boards
• Quick NCV checks for live circuits

Good to know

The meter is powered by two AAA batteries (included) and features an auto power-off function to conserve battery life. It meets CAT II 600 V and CAT III 300 V safety standards, making it suitable for use on branch circuits and fixed equipment. The compact size and protective holster (if included) make it a durable choice for daily field use.
