HYDRO-1
Color
Change Developer
HYDRO-2
Concentrated Leak Tracer
a two-part system for testing for cold water leaks in a humid atmosphere
|
|
|
APPLICATIONS
Testing of large tanks, vessels, complex piping systems,
flexible containers and systems that inherently contain or will
contain water. It can also detect leaks in valves, fittings and
welds. It is formulated to prevent false indications due to high
moisture in the air or cold piping that can condense water on
its surface.
Hydro-1 is a color change developer sprayed on the outside of a
potential leak site. Hydro-2 is a liquid tracer which goes into
solution with the test water. Hydro-2 causes a visible color
change when it comes in contact with the Hydro-1 developer.
BENEFITS
• The method can be used to locate leaks as part of a quality
control test or a field inspection procedure.
• It is quick and inexpensive, making it the best solution for
testing large or complex systems.
• It is very sensitive so it can be used in the most demanding
applications.
• It requires a minimal of pressure differential, making it
ideal for many difficult applications.
• It is easy to take photos of the test results, making work
easy to substantiate.
• Can be made highly corrosion resistant with CI25 Corrosion
Inhibitor Additive.
• Sensitivity can be increased using
CIM-200 as an additive to lower surface tension of water.
SPECIFICATIONS
Sensitivity: 1 x 10-3 atm.cm3/s (1 x
10-4 atm.cm3/s with CIM-200
)
Temperature Range: 2oC to 93oC
Humidity Range: 0 to 90% non-condensing
Oxygen/Vacuum: Does not require oxygen or air to operate
Color change: Orange to purple
Storage Life: 2 years from shipment
METHOD DESCRIPTION
Dilution ratio: 50 gallons water to 1 gallon tracer for
immediate use or 25 gallons water to 1 gallon tracer for long
dwell time.
1. For best results pour Hydro-2 into tank or vessel to be
tested and add water to correct volume.
2. Spray a coating of Hydro-1 Developer on outside of weld,
joint or surface where leakage is a concern. Allow to dry at
least 15 minutes.
3. Once the activating tracer has been given sufficient soak
time to permeate the test piece and enough dwell time is allowed
for the tracer
to penetrate to the surface treated with developer, an obvious
color change from orange to purple will take place at the point
of leakage.
4. To remove, wipe with a damp cloth. |

PACKAGING Hydro-1 is available as a 12 oz aerosol spray can, and gallon
cans. Hydro-2 is available in gallon bottles, 5 gallon pails &
55 gallon drums.
