Voltage Detectors, as the name implies, are used to check for the presence of voltage in and around an object or surface. It works by detecting the electric field flux lines. These detectors examine voltages in power lines, lighting fixtures, wires, and circuit breakers, among other things. Non-contact Voltage Detectors, neon Voltage Detectors, solenoid Voltage Detectors, digital Voltage Detectors, and pen-style Voltage Detectors are all available on the market. Voltage Detectors are increasingly employed in battery voltage monitoring, microprocessor reset, switching circuits in battery backups, and locating problem connections due to their lower maintenance and compact design. As a result, throughout the projected period, the global voltage detector market is expected to reach US$ 4.42 billion.
