Content | The Amprobe SC-3500 4? Signal Clamp for AT-3500 attaches around a buried metallic pipe, cable, or wire to induce a transmitted signal into the feature for active location and tracing. It does not require direct contact with metal to transmit the signal and can transmit signal through insulation on wires and into cable and wire bundles, providing more accurate tracing than locating with just a receiver and transmitter. Accommodates conductors up to 4? in diameter. Transmits a 33 kilohertz (kHz) frequency supplied by the T-3500 Transmitter (included in the AT-3500 kit). | Amprobe Flex Current Sensor Developed for the Amprobe DM-5, your all-in-one solution for excellent power quality. | Universal, economical tachometer measuring rotational or surface speed either in contact or non-contact way. Widely used to measure rotational speed of motors, conveyer belts and other moving or rotating systems. | If you install or connect 3-phase motors and systems, you recognize the importance of verifying the correct motor rotation and wiring phase sequence. Improper connections can cause motors to rotate in reverse direction, potentially damaging the motor and the equipment it is powering. | Eliminate downtime, predict the lifetime of equipment and reduce safety hazards with the Amprobe AMB-55 Insulation Resistance Tester that tests voltage and step voltage to 5,500 V. You can accurately test cables, transformers, motors, surge arrestors and generators in noisy environments such as high voltage switchyards. It also boasts built-in noise rejection filters and shielded test leads to provide high EMI immunity | TEST LEAD SET FOR INSULATION RESISTANCE TESTERS |
