Our range of UV lamp kits for leak detection

Fluotechnik offers several configurations for observing fluorescent tracers directly in the field. The choice depends primarily on the tracer to be detected and the conditions in which inspections are carried out. For occasional close-range inspections, a compact configuration may be sufficient. For regular professional use, longer battery life, greater mobility and transport or protective accessories may become important considerations. The working environment also matters: observation distance, ambient light, accessibility of the areas to be inspected and frequency of use all influence the choice of lamp.

Depending on the model, kits may include:

  • A portable UV lamp
  • A battery or power accessories
  • Glasses suited to fluorescent inspection
  • A charger
  • A carrying case
  • Various accessories for regular field inspections

What is a UV lamp used for in leak detection?

A UV lamp does not detect a leak directly. It reveals the fluorescence of a tracer that has previously been introduced into the fluid. When the fluid circulates or escapes into an accessible area, the fluorescent product may leave a trace or appear on a surface. UV lighting increases the contrast, making it easier to identify.

This method can be used to inspect:

  • Pipes and plumbing networks
  • Compatible heating circuits
  • Sewer systems
  • Roofs, terraces and waterproofing structures
  • Basins and swimming pool circuits
  • Oil circuits
  • Fuel circuits
  • Chillers and air conditioning systems
  • Industrial machinery and equipment

The lamp and tracer therefore work together. A product suited to the fluid and installation must first be selected, followed by lighting with characteristics that allow its fluorescence to be clearly revealed. A professional who already has suitable tracers can simply add an appropriate UV lamp to their equipment. When the requirement covers the entire protocol, however, a more complete kit including tracing products, dosing accessories and detection equipment may be more practical.

How do you use a UV lamp with a fluorescent tracer?

A UV inspection begins well before the lamp is switched on. The quality of the result depends on the tracer selected, its dosage, circulation time and the conditions under which the area is inspected.

Step 1 - Identify the fluid and installation

Begin by determining exactly what needs to be inspected:

  • Water
  • Oil
  • Fuel
  • Refrigerant
  • Another technical fluid

The type of installation must also be identified: pipe, tank, engine, refrigeration circuit, air conditioning system, industrial equipment or another system. The tracer and detection equipment must both be suitable for these parameters.

Step 2 - Select a compatible fluorescent tracer

Not all fluorescent products emit the same signal.

Before the operation, check in particular:

  • The type of fluorescence produced by the tracer
  • Its compatibility with the lamp
  • The fluid in which it will be used
  • The expected concentration
  • The observation conditions
  • Any specific product recommendations

A lamp that is properly matched to the tracer will generally provide clearer detection than equipment selected solely on the basis of power.

Step 3 - Prepare and dose the product

The quantity of tracer depends in particular on:

  • The fluid volume
  • The length of the circuit
  • The flow rate
  • The expected dilution
  • The likely size of the leak
  • The required level of fluorescence

The product is then introduced at the point defined in the protocol.

Step 4 - Allow the tracer to circulate

The product must have enough time to travel through the installation and, where a leak or recovery point exists, reach the area being investigated.

The required time can vary significantly depending on:

  • The circuit volume
  • The flow rate
  • The pressure
  • The length of the pipes
  • The operating conditions
  • The size of the leak

Step 5 - Prepare the observation conditions

Fluorescence is easier to distinguish when there is sufficient contrast with the surrounding light.

Whenever possible:

  • Reduce ambient lighting
  • Work in a shaded area
  • Shield the inspection area from direct light
  • Move the lamp closer to the surface
  • Clean dirt or deposits that could interfere with detection

On some sites, these simple precautions can significantly improve signal visibility.

Step 6 - Inspect suspicious areas methodically

The UV lamp can then be used to inspect:

  • Fittings
  • Seals
  • Pipes
  • Valves
  • Heat exchangers
  • Mechanical components
  • Surfaces
  • Tanks
  • Outlets
  • Areas already identified as potentially problematic

Localised fluorescence may indicate the passage or presence of the marked fluid.

Step 7 - Check the origin of the signal

Not all fluorescence necessarily indicates an active leak.

A surface may retain:

  • An old product trace
  • Residue from a previous inspection
  • Contamination
  • Naturally fluorescent deposits

If there is any doubt, clean the area where the protocol allows it and carry out another inspection after the tracer has been circulated again.

Step 8 - Confirm before carrying out repairs

Fluorescence helps narrow down the diagnosis, but it must be interpreted alongside the circuit layout, circulation time and other observations available. This confirmation is particularly important before carrying out a repair or dismantling equipment.

What is a UV lamp used for in leak detection?

It reveals the fluorescence of a compatible tracer introduced into a network or circuit. When the marked fluid reaches an accessible area, the lamp can help identify its presence and narrow down the leak search.

Not as part of a fluorescent tracing diagnosis. The lamp reveals a fluorescent signal that is already present. It does not automatically make every fluid or leak visible.

No. Visibility depends in particular on:

  • The tracer
  • The lamp spectrum
  • The concentration
  • The dilution
  • The observation distance
  • Ambient light

Compatibility between the product and the lamp should be checked before the operation.

Yes, but strong ambient light can significantly reduce the contrast of the fluorescent signal. A shaded area, protection from direct light or inspection in a darker environment generally makes detection easier.

Not necessarily. A visible dye can be observed directly with the naked eye. A UV lamp becomes useful when the product has usable fluorescence or when the diagnosis relies on fluorescent detection.

Depending on the tracer selected, it can support diagnostics on:

  • Water networks
  • Plumbing installations
  • Heating systems
  • Sewer networks
  • Swimming pools
  • Roofs and waterproofing systems
  • Oil circuits
  • Fuel circuits
  • Refrigeration systems
  • Air conditioning systems
  • Industrial equipment

The choice mainly depends on:

  • The tracer used
  • The required spectrum
  • The observation distance
  • The useful light output
  • The lighting conditions on site
  • The required battery life
  • The required mobility
  • The frequency of use

This can be useful when a surface contains old residues, dirt or deposits that may produce interfering fluorescence. However, care should be taken not to remove the trace being investigated. Cleaning should therefore be adapted to the protocol and the stage of the diagnosis.

An initial inspection can identify a fluorescent area. If necessary, the area can then be cleaned and checked again after the tracer has circulated. If fluorescence reappears, this helps confirm that the product is continuing to reach the area.

Follow the manufacturer’s instructions and use the recommended protective equipment. In particular, avoid unnecessarily directing the UV source towards the eyes or skin.

Choosing the right UV lamp kit for fluorescent inspections

A UV lamp is an essential part of the equipment when a diagnosis relies on a fluorescent tracer. Its role is to improve signal contrast and make traces easier to detect.

The choice of equipment mainly depends on:

  • The fluorescent tracer used
  • The fluid: Water, oil, fuel, refrigerant or another technical fluid
  • The type of installation
  • The spectrum required to reveal the product
  • The distance between the lamp and the inspected area; the useful light output
  • Ambient light; the required battery life
  • The weight and ergonomics
  • The accessories required
  • The frequency of use

A close-range inspection in a dark space does not require the same characteristics as an inspection carried out on a large machine, vehicle, outdoor network or brightly lit site. The complete protocol must also be considered. Even with a high-performance lamp, too little tracer, significant dilution or insufficient circulation time can make recovery difficult to observe. For professionals who already have their tracers, a lamp and its accessories may be all that is needed to complete the equipment. For those who also require tracing products and dosing equipment, a complete kit designed for the relevant fluid will generally be more practical. Fluotechnik helps you select the configuration best suited to your applications and working conditions.
