A videoscope includes a sensor end having an image detector and at least one sensor selected from the group consisting of an eddy current sensor, an ultrasonic sensor, or an array of such sensors, a handle; and an elongated arm that comprises a conduit that connects the sensor end to the handle. The conduit houses a link that transmits image information from the image detector through the conduit, and the conduit further houses at least first and second working channels that extend from the sensor end to the handle. Fluid injected at a handle end of the conduit passes through the first working channel, out the sensor end, and onto the surface under examination. The second working channel contains the eddy current or ultrasonic sensor and passes their signals through the conduit.
