Clamp-on meters
Clamp meters are designed for AC, DC, and AC/DC environments.
- Multi-function clamps feature essential test tools built right in such as a non-contact voltage detector, single and dual thermocouple thermometers, and a patented, exclusive built-in IR thermometer.
- For very low current readings, our mini clamp meters offer high resolution accuracy and smaller size for access into smaller areas.
