  • Advanced AC Filtered Tone and Probe Kit

    Pro220K - Armada Technologies

    The Pro220K tone generator and probe kit is designed to help contractors easily identify the termination point of any wire. Tone and probe technology has been around since the 1970's, but not like this. Advanced features including AC filter noise rejection, headlight, low battery light, combination metal/plastic tips, etc. make the Pro220K one of the most advanced tone/probe kits ever. Uniquely, the Pro220K uses AA batteries, providing tremendous battery life.

  • Under/Overvoltage Monitors

    Acopian Technical Company

    Contacts to control an external horn or light, or to signal your PLC are now available on independent accessories for any power supply. These modules can be used on power supplies with DC voltages from 5 to 125 Vdc. SPDT relay contacts switch if the power supply’s output deviates by:*1.0 volt or more (for 5 volt outputs)*2.0 volts or more (for 6 to 48 volt outputs)*3.0 volts or more (for 49 to 125 volt outputs)

  • Voltage Detector

    ZhangZhou Weihua Electronic co.,ltd

    A device that tells the user whether an object has an electrical charge. It can be a simple, pen-shaped piece of testing hardware that indicates the presence of electricity, or it can be an advanced tool used to detect precise voltage levels in electrical systems. Voltage detectors use either visual or audio cues to tell the user whether voltage is present. Some are equipped with lights and numbers that indicate the level of voltage, while a less advanced voltage detector might simply make a beep to indicate that a level of detectable voltage is present.

  • Voltage Detectors

    Salisbury

    Self-Testing Voltage Detectors are used to verify live or de-energized conductors. These testers may be used with rubber insulating gloves or hot sticks using the splined universal end fitting. Testers indicate the presence of voltage with an extra bright LED light and a distinctive audible signal. It is recommended that the tester be moved closer to the conductor until a warning is indicated, or it touches the conductor, apparatus, or elbow test point. Each tester requires three “C” batteries (included).

  • Voltage-Pen-Detector

    A-SUN TEST LTD.

    Are a relatively simple testing instrument that enables electricians and other uses tolocate, trace and identify common electrical problems. These testers can locate wires behind walls, underground,and inside junction boxes. Others are designed to find blown fuses or test light fixtures. Some testers can evenlocate neutrals, ground faults, and high voltage lines without interrupting power
