Cleaning Accessories:

DT640 Utility Vacuum

The vacuum suction head can be mounted on a dual actuating arm in front of the DT640. One actuator tilts the head 20 degrees, and the other raises and lowers the head 20 degrees. The vacuum head concentrates suction on the bottom of the tank to focus pumping on the sediment. The hose is connected to a submersible pump outside the tank. A camera on the tracker’s main body monitors the vacuum head as it removes debris. The multi-purpose vacuum pack does not include a hose or pump.

DT640 Pressure Washer Kit

Choose from three different pressure washer kits, 310mm, 500mm, and 1000mm. For optimal cleaning, the integrated arch kit can raise, lower and rotate the spray head by 20 degrees. In addition, the head supports a pressure washer unit with up to 4000 PSI. Hoses and pressure washer is not included in the DT640 pressure washer kit.

Inspection Accessories:

Cygnus Ultrasonic Thickness Gauge

A Cygnus ultrasonic thickness gauge can be integrated with your DT640, allowing you to take thickness readings on steel tanks, hulls, or other metal surfaces without consulting a dive team or draining an asset.

The Cygnus probe can take readings through up to 1/2″ or 12mm of soft marine growth or coatings.
