A moisture testing device having various applications including the testing of moisture in the thermal insulation of insulated pipe, the device having a readout and related components connected to a detector assembly which is pivotally mounted at the end of an adjustable pole. The detector assembly utilizes the principle of neutron back scatter or neutron moderation which is known for measuring water and hydrogen, but it is designed as a highly efficient screening device which can for example test thousands of feet of pipe in a day.
