The FLIR VP50 is a tough, CAT IV-rated Non-Contact Voltage Detector featuring a combination of alerts – including tactile vibration, red LED alarms, and a powerful LED worklight so you’ll never miss the presence of voltage even in dark or noisy areas. Engineered to reliably detect voltages on the latest tamperproof outlets and electrical systems installed using modern construction methods, the VP50 is useful when both working with safety outlets or detecting voltage in high powered equipment and low voltage systems.
