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

WHERE ARE COLORMETRIC LEAK TESTERS USED?
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).

TRACER	COLOR CHANGE	PRODUCT #	APPLICATION METHOD
Colormetric Precleaner		ADP-PC	Precleaner
Ammonia	Yellow to Blue	ADP-219	Aerosol spray
Ammonia	Yellow to Blue	ADP-319	Paint
Ammonia	Smoke	ADS-100	Aerosol spray
Water	White to Green	W-15A-M	Adhesive-backed treated paper
Water	White to Green	W-15A	Treated paper (no adhesive)
Water	White to Green	WDP-217	Aerosol spray
Chlorine	White to Yellow	CDP-100	Aerosol spray
Oil	White to Red	ODP-110	Paint
Oil	White to Stain	ODP-210	Aerosol spray

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.
