Leak-Tec: Thin Film Bubble Testing Solutions
Thin film leak testing is the most common and
one of the most reliable methods of detecting and locating
leaks. Thin film bubble testing has many inherent
• It is easy to
use and requires little operator training.
• It is inexpensive to use and not subject to break down
like complex instrumentation.
• It operates immediately and continues to give
• It can be extremely sensitive, finding leaks down to
1 x 10-6 (.000001) standard cc/second. The
equivalent of losing a pound of Freon every 2,700 years.
Sonic 3000: Ultrasonic Leak Detector
Leaks and other vibration sources produce a very broad band
of ultrasonic noise. This frequency is well above the sounds
which the human ear can hear. The Sonic 3000 has been set to
translate those frequencies into an audible output. It can
be used to solve a number of different maintenance and
of the Sonic 3000:
• It can be used to detect a flow or leak of any gas or
• It can detect leaks rapidly and at distances up to 100
• It requires little operator training
• It can locate internal as well as external leaks.
• It can accurately locate vacuum or pressure leaks
• It makes irregular, shaped or very large fittings easy
• It can detect internal arcing from faulty electrical
• It works at low and high temperatures
• It can find intermittent leaks which many other
• It can detect leaks in overhead lines, buried pipes and
in unpressurized areas.
• Its versatility means increased employee productivity
and less need for costly specialized equipment.
• It is portable, passive, non-destructive, non-intrusive
and requires no cleanup.
By lowering the surface tension and increasing the wetting
ability of water, a leak in a pressurized immersed vessel
will generate a steady stream of tiny bubbles instead of an
occasional larger bubble as with untreated water. Small
leaks will produce bubble indications that are impossible
with normal water. The CIM series will not foam, will not
support bacteria growth and are formulated to prevent
corrosion. Although their use is recommended with deionized
water, they are chelated to be compatible with hard water.
Immersit additives are biodegradable.
Tracer Dyes are mixed with water or oil to be tested for
leakage at its source. If the dye appears where there may
have been a leak, the leak is proven. Tracer dyes are used
in rivers, in toilets, in oil pipelines, and sewer systems.
Handheld Gas Tracers
Tracers are available depending on the gas to be found.
These tracers are:
• Sensitive - well below the OSHA limits and lower explosive
limits. In some gases the tracers will detect gases in
quantities as low as one part per million.
• They have been designed to be low maintenance and easy to
• They are dependable, tough and rugged.
• They are priced to be AFFORDABLE
• They are designed to be easy to operate and learn.
Personnel Protection Indicators
Wearable and Disposable.
Protect yourself against dangerous gases with an instant
reading detector. An immediate color change is shown in the
presence of specific toxic gases.
Indicators are available for the following toxic gases:
• Carbon Monoxide
• Nitrogen Dioxide
• Hydrogen Sulfide
PiNPOiNT Colormetric Developers
Colormetric leak testing is useful for locating and
measuring gas leaks either as a quality control test for as
a field inspection procedure. It can be used to test
critical parts or containers that will hold toxic or
explosive gases or liquids or as a quick test for other
Colormetric developers are paints that are sprayed or
brushed onto the welds and joints of a container. A tracer
gas is introduced inside the container. Where a weld or
joint is leaking, the outside paint changes color to clearly
indicate where a leak is present. AGC offers several
Ammonia Developer. To be used with ASNT Standard E1066,
Standard Test Method for Ammonia Testing.

SBG-200 Wall Mounted Gas Monitor
Monitor over 100 combustible and toxic gases including:
Ammonia, Butane, Carbon Monoxide, Ethylene Oxide, Gasoline,
Hydrogen, Methane, Propane, Natural Gas, Sulfur Dioxide,
Formaldehyde, Benzene, Acetone.
The SBG-200 is a solid state, completely self-contained
monitor capable of detecting gases. Several sensors are
available which allow it to be calibrated to alarm at gas
concentrations well below their lower explosive level or
OSHA ceiling. The monitor provides its own visual and
audible alarms as well as meter indication of gas
concentrations. A relay contact is provided to allow the
SBG-200 to connect with a central alarm system or turn on
Flaw Finder Inspection Penetrants
Inspection Penetrants are a safe, sure, fast, easy sensitive
low cost way to find hidden defects in any non-porous solid.
All metals can be tested in this way. Penetrants highlight
flaws and leaks that are open to the surface and are too
small to see by normal visual inspection. Inspection
penetrants show the presence, location, nature and size of
defects. Penetrants are convenient. They can travel anywhere
in the field or be used where work space is limited.
Penetrants can be used on very large or complex items,
indoors or outdoors.
Penetrants are used worldwide by quality control, welding,
NDT and maintenance personnel. Almost all industries which
work with metal rely partially or exclusively on inspection
penetrants. Some of these industries are: engine
manufacturers and rebuilders, ship builders, train builders,
primary metal producers, metal fabricators, machine tool
TSI-301 is a specially formulated lubricant which sinks into
the pores of metal. Very little is required to take
advantage of its excellent lubricating properties. Even when
the surface of metal appears to be dry, the TSI-301 is
present, doing its job. It creates a thin film which tends
to uproot corrosion or contaminants. It bonds itself to the
surface of the metal through physical adsorption reducing
surface tension, practically eliminating friction and
reducing wear. It does not build up into gummy deposits.
Some advantages over other lubricants are:
Cleans away rust and contamination better
• Low viscosity means
• Does not attract dust, dirt or lint
• Displaces water
• Increased wear
• Wider temperature range (-60°F to +450°F)
• Reduced residue
• Less flash and fire hazard. It has
no flash point.
It is safe to use near fires and hot metals.
• Withstands extreme pressure
• Does not conduct electricity (anti-static)
• Prevents seizure
• Will not stain
Fluoro-Finder III Shot Peen Tracer
Shot Peening improves metal and weldment resistance
to fatigue, stress corrosion cracking and galling. To
provide this benefit, it is important that shot peen
coverage be uniform and complete. A liquid tracer
(Fluoro-Finder III) provides a coating which is removed at a
rate proportional to peening coverage, providing visual
feedback on the uniformity and completeness of peening
coverage. Fluoro-Finder III, has a pigment which fluoresces
under ultraviolet light making the determination of the
degree or percentage of coverage quick, easy and foolproof.
Use of this tracer eliminates the need for 200-percent
coverage in order to be assured of complete peening.
