Product description
UNI-T UT139C is a True RMS digital multimeter developed for electricians, electronics workshops, servicing, and troubleshooting. The instrument is rated CAT III 600V and features automatic range selection (autorange) as well as an NCV function for non-contact voltage detection. The built-in 31-segment bar graph provides a clear analog-style representation of measurement values alongside the digital display.
Example applications:
- Measurement of current and voltage (AC and DC)
- Checking fuses and components
- Troubleshooting electronics and electrical installations
- Resistance and continuity testing
- Capacitance and frequency measurement
- Temperature measurement using the included temperature probe
- Non-contact voltage detection (NCV) of live conductors in walls, cables, etc.
