SPECTROLINE

Spectroline is a brand of leak detection and nondestructive testing equipment manufactured by Spectronics Corporation, a company founded in 1955 and based in Westbury, New York. The brand's product line centers on fluorescent dye additives, ultraviolet and violet light inspection lamps, and ultrasonic leak detectors used to locate leaks in refrigerant, glycol, oil, and compressed-gas systems. Spectroline products are used in HVAC and refrigeration service, industrial maintenance, automotive repair, and fluid-power diagnostics. The core technical approach is straightforward: a fluorescent dye is introduced into a closed system, circulates with the working fluid, and escapes at leak points; when the area is illuminated with a UV or violet light source, the dye fluoresces to make the leak visible. For systems where dye injection is impractical, ultrasonic detectors convert high-frequency sound from pressurized gas or vacuum leaks into audible or visual signals. 3G Electric supplies Spectroline leak detection dyes, UV inspection flashlights, dye injector kits, and ultrasonic detector kits to maintenance and procurement teams worldwide. The product range includes water-based and oil-based dye formulations, cartridge and bottle packaging, and lamp options powered by Li-Ion, AAA, or C-cell batteries. Several kits bundle a dye cartridge, an R-410a adapter, a UV LED light, and fluorescence-enhancing glasses in a single package. Dye cartridges are available for specific refrigerant groups, including CFC, HFC, and ammonia systems, and for glycol and oil-based fluid circuits. The Water-Glo dye line carries NSF certification for use in glycol systems where potable-water contact is a consideration. Ultrasonic detector kits are CE certified and include the necessary accessories for leak surveying in compressed air lines, steam traps, and sealed enclosures. 3G Electric supports the Spectroline line by stocking individual components and complete kits, providing specification-level product data, and coordinating global shipping for industrial buyers. The catalog includes replacement dye cartridges, injector assemblies, and lamp accessories so that maintenance programs can standardize on a single leak detection method across multiple sites. For procurement specialists, the availability of both dye-based and ultrasonic methods from one brand simplifies vendor management and ensures compatibility between dyes, injectors, and light sources. Plant engineers specifying leak detection for refrigerant circuits, compressed air systems, or hydraulic lines can select from Spectroline products based on the working fluid, system volume, and the type of leak indication required. The brand's long production history and focus on fluorescent and ultrasonic leak detection make it a common reference point in maintenance procedures across HVAC, refrigeration, and general industrial applications.

Frequently asked questions

Common questions about SPECTROLINE from 3G Electric.

What is the difference between Spectroline Water-Glo and Oil-Glo fluorescent dyes?

Water-Glo dyes are water-based formulations intended for glycol and water-containing systems, such as chilled-water loops and HVAC hydronic circuits. The Water-Glo SPI-WGG-16 is a green dye supplied in a 16 oz bottle and carries NSF certification. Oil-Glo dyes are oil-based and designed for petroleum-based fluids, including lubricating oils and hydraulic fluids. The Oil-Glo kit (SPI-VLOGYG) includes an 8 oz twin-neck bottle of dye, fluorescence-enhancing glasses, and a violet light LED flashlight. Selection depends on the fluid in the system: use Water-Glo for water or glycol, and Oil-Glo for oil-based fluids. Mixing dye types across incompatible fluids can reduce fluorescence or fail to circulate properly.

Which Spectroline dye cartridge should be used for ammonia refrigeration systems?

The Spectroline EZ-Ject fluorescent dye cartridge SPE-EZ100E-CS is specified for ammonia refrigerant groups. It is a 0.5 oz cartridge that injects into the refrigerant circuit; under UV light, escaping dye fluoresces to indicate leak locations. Ammonia systems require dye formulations compatible with the refrigerant and system materials, so using a cartridge rated for ammonia is necessary. This cartridge is part of the EZ-Ject series, which uses a injector assembly to introduce dye into a closed circuit without opening the system to atmosphere beyond the injection point. Confirm compatibility with the specific system pressure and refrigerant charge before use.

What is included in the Spectroline GLO Seal EZ-Ject dye injector kit SPE-MVLEZDS?

The SPE-MVLEZDS kit is a GLO Seal EZ-Ject series dye injector kit for CFC refrigerant systems up to 14 tons. It includes a 0.5 oz green dye cartridge, an R-410a adapter, and a UV LED light powered by AAA batteries. The kit is designed to inject fluorescent dye into the refrigerant circuit, where it circulates and escapes at leak points. The UV LED light makes the dye visible at the leak site. The R-410a adapter allows connection to systems using that refrigerant. This kit is intended for HVAC and refrigeration service work where a self-contained dye injection and inspection set is needed.

How does the Spectroline ultrasonic leak detector SPI-MDT work?

The SPI-MDT ultrasonic leak detector converts high-frequency sounds produced by air, gas, or vacuum leaks into audible signals. It is CE certified and includes Windows software, though the unit itself has no display. The detector is used to pinpoint leaks in compressed air lines, steam traps, and sealed enclosures. Because ultrasonic detection relies on the sound of the leak rather than a dye, it does not require introducing any substance into the system. This makes it suitable for applications where dye injection is impractical or where the system cannot be opened. The kit includes the necessary accessories for surveying equipment and piping.

What battery types do Spectroline UV inspection flashlights use?

Spectroline UV inspection flashlights are available with different battery configurations. The SPI-LTPR leak detection lamp uses a Li-Ion battery and includes batteries and a carrying case. The SPI-LTP ultraviolet inspection flashlight operates on C batteries, which are included, and comes with UV absorbing glasses. The UV LED lights included in dye injector kits, such as the GLO Seal EZ-Ject kits, typically use AAA batteries. Battery type affects runtime and replacement logistics, so maintenance programs may standardize on one configuration. All listed lamps include batteries at supply, and some include UV absorbing glasses for eye protection during inspection.

Can Spectroline leak detection dyes be used in systems with potable water contact?

The Spectroline Water-Glo fluorescent dye SPI-WGG-16 is NSF certified, which indicates it meets requirements for use in applications where contact with potable water is a consideration. This certification applies to the Water-Glo water-based dye formulation. Other Spectroline dyes, such as Oil-Glo or the EZ-Ject cartridges for refrigerant systems, are not indicated for potable water applications. When selecting a dye for a glycol or water system that may contact potable water, verify that the specific product carries the appropriate certification. The Water-Glo dye is supplied in a 16 oz bottle and is green in color.
