Battery powered hatch cover leak detector transmitter

The hatch sure transmitter is a powerful, battery operated, ultrasound transmitter with 19 x 40 KHz elements. The transmitter can be placed in the bulk carrier hold where it will the fill the hold with ultrasound and any ultrasound that escapes, through gaps in damaged areas of the hatch cover seals, can then be detected by the hatch sure receiver. The transmitter has six selectable pre-set power levels to give variable output allowing the unit to be used in confined spaces, such as testing watertight doors.
