Review on ⚡ Southwire Tools 40116N NCV Detector 100-600V AC: Accurate Voltage Detection for Electrical Safety by Jerome Pernell
very clear signal - Electrical
I have found that many non-contact voltage testers are not reliable and have some fuzzy noises and lights. This device glows green when powered on, loud and flashes red when power is present. Very clear readings. Mine is more sensitive than its rating and picks up low voltage coming through the bezels from the phone charger or outlets. I like it much better than my small nc tester.
- Sturdy construction
- Has flaws
