Choosing the Right Voltage Tester: Key Features to Consider
Safety Ratings (CAT II, III, IV) and IP Protection - Ensure your tester meets the right category rating for your work environment and includes IP protection against dust and moisture.
Voltage Range and Sensitivity - Look for testers that cover both low and high voltage ranges, with reliable detection sensitivity for accurate results.
Display and Alerts - Choose between LED, analog, or digital displays, and ensure your tester has clear visual and audible alerts for live voltage.
Rugged Build and Durability - Field use demands tools that last. Look for drop-tested, impact-resistant designs with protective casing.
Advanced Functions - Need more than voltage? Go for testers with continuity testing, phase rotation, or current detection capabilities.
