Nu-Calgon chemical gas leak detectors have the proper viscosity in order to remain on the surface and facilitate the formulation of the bubbles. They are noncorrosive to the metal surfaces of the piping and fittings and are functional at low temperatures (freeze-protected) as well as high or elevated temperatures

• Regular leak detector not recommended for use with oxygen systems
• Regular leak detector and Cal-Blue will not leave flourescent residue affecting black light systems
