  PiNPOiNT Colormetric Leak Testing  

Colormetric detectors are rapid leak detectors and inexpensive to use.  They react
chemically with minute leaks causing a visible color change in the developer.
They can be used to detect leaks up to 1x10-7 Std cm3/s

Colormetric developers are used to leak test large single and double walled tanks, pressure and vauum vessels, laminated, lined or double-walled parts, complex piping systems, flexible containers (such as aircraft fuel tanks), glass-to-metal seals in hybrid packages and systems that inherently contain or will contain the tracer (water, ammonia, chlorine or oil).

How to Use Colormetric Leak Detection Developers
Make sure the interior and exterior welds and joints where leaks are often found are free of oil, grease, flux, slag, paint or other contaminants that might temporarily block or mask leakage.
Apply developer to weld, joint or surface where leakage is of concern.
Allow to dry.
Once activating tracer has been given sufficient time to permeate the test piece and enough dwell time is allowed for the tracer to penetrate to the surface treated with developer, the specified color change will take place at the point of leakage.
To remove, wipe with a damp cloth.
