CT40

The CT40 from Extech Instruments is a cable tester and digital multimeter. The CT40 is a cable tester which uses a transmitter/receiver to allow for wire identification of an individual core to the end of a multi-core cable. The meter’s digital multimeter functions provides for easy measurement of AC/DC voltage, AC/DC current, resistance, continuity and diode check. This device is shipped fully tested and calibrated and with proper use, will provide years of reliable service.
