Summary: | A reusable indicating material for detecting leaks in sealed structures and other closed bodies comprises a fabric saturated with an indicator solution containing an acid-base indicator, a surfactant, a buffering system and a humectant. The indicator solution remains reactive when the fabric is dry to the touch and will indicate the presence of leaks in the structure being tested by changing color when a reactive gas escapes from the structure being tested. Upon removal from the tested structure the indicator material reverts to its original color and is available for subsequent tests. |
