ABSTRACT:
A fluid detector that senses fluids, activates an alarm and preserves a sample of the fluid for laboratory or on-site testing. The fluid detector includes a first container having a sealable cap and a fluid-passing portion, a second container disposable within the first container for collecting and storing a sample of the fluid. The detector can contain a fluid-responsive material which undergoes a change upon contact with the fluid. The change in the fluid-responsive material causes the second container to be sealed. The second container can contain a fluid collector so that the fluid can be analyzed.
