Extech HDV640 High Definition Borescope

The Extech HDV640 High Definition Articulating VideoScope can be used to peer into tight spots, record and playback real-time video and images. Typical applications include HVAC inspection, automotive inspection, cable routing, and automotive/boat/aircraft inspection. It has a 6mm diameter camera positioned on a semi-rigid 1m cable that provides images to the Extech HDV600 Monitor Unit.

The 6mm diameter camera is placed on the end of a semi-rigid 1m cable and has an articulated head that can rotate through 240˚ so that the user can gain a complete picture of the environment under inspection. Rotation is controlled by the control unit which means that the user can swivel the view even when the head is inside the target area. The Extech HDV640 uses a macro lens which can focus on objects that are between 20mm and 60mm from the lens and integrated LED lights illuminate the camera’s surroundings.

Video and images can be viewed live or played back on the 5.7” colour screen of the Extech HDV600 Monitor Unit. It has a 640 x 480 pixel resolution allowing it to show ultra-detailed high definition pictures from inside the target area. The excellent lighting options for the screen make it easy to view in sunlight or in darkness.

Up to 15,000 images or four hours of video can be saved to the 2GB SD card which is supplied with the Extech HDV620. The SD card format is very easy to transfer and the user can even add voice annotations so that observations can be made without pausing filming or observations.

Both the camera (IP57) and the Extech HDV600 Monitor (IP67) are fully waterproof for use in applications such as plumbing and pest control. The monitor unit is also shock-proof for drops of up to 2m. The push buttons that operate the Extech HDV640 are extremely easy to use for both right- and left-handed uses whilst the camera rotation control unit is specifically designed for use with gloves.
