Our extensive line of voltmeters and phasing sets are designed to measure AC and DC voltages on conductors from phase-to-ground and phase-to-phase. These instruments also allow the user to determine if two conductors are in-phase or out-of-phase with one another. There are numerous models available with different ranges to assure the best possible range for easy readings. All models are designed for use on overhead lines and are adaptable for use on underground systems by using accessory probes. Our analog line of voltmeters and phasing sets include the MARK® and EM series. Our digital line of voltmeters and phasing sets include the DigiVolt® series. All of the voltmeters and phasing sets feature universal splines for mounting onto hot sticks and easy-to-read displays.
