Tellegloww Automotive AC Leak Detector Kit — R134a/R410A/R22 Refrigerant Sniffer with UV Dye Injector & Protective Glasses

Tellegloww Automotive AC Leak Detector Kit is a handheld electronic refrigerant sniffer and UV dye injector bundle designed to quickly locate leaks in R22, R134a, R404a, R410A and most halogenated refrigerant systems.

This all-in-one kit combines an adjustable electronic leak detector with a compact dye injector syringe and protective UV glasses so you can find and confirm leaks in vehicle air conditioning systems without a shop visit. Lightweight and built from durable materials, the kit is set up for field use: the detector powers up in seconds, the probe reaches tight spaces, and the UV glasses protect your eyes while you inspect dye-traced areas under ultraviolet light.

How does the electronic sniffer detect refrigerant leaks?

The detector uses an advanced sensing element tuned to halogenated refrigerants. When the probe encounters escaping refrigerant, the unit emits an audible tone and flashes a visual indicator; higher leak rates increase tone speed and flash frequency. You can adjust sensitivity to home in on small leaks or screen broad areas quickly.

• Detects HFC, CFC, HCFC families and common blends.
• Fast warm-up—ready to scan in about 6 seconds.
• Variable sensitivity control for fine or coarse detection.
• Extendable probe reaches tight joints, fittings and evaporators.

What’s the easiest way to use the dye injector with my car’s A/C?

The injector syringe connects to the low-side service port; slowly turn the syringe handle to introduce the UV oil dye into the system until you reach the desired amount. After running the system to circulate the dye, inspect suspect areas with the included UV glasses and the detector probe for confirmation.

• 1/4" brass SAE-compatible quick connectors for a secure fit.
• Aluminum-alloy syringe body for durability during field use.
• Simple manual control—inject gradually to avoid overfilling.
• Works with standard low-side service ports on most vehicles.

How do the UV glasses and dye help pinpoint leaks?

The UV dye marks escaping refrigerant with a fluorescent trace that’s visible under ultraviolet light; the included UV-protective glasses improve contrast so you can spot dye stains faster and safer. Use the sniffer to locate general leak areas and the UV glasses to visually confirm the exact leak site.

• Protective lenses shield eyes from debris and strong light during inspection.
• Enhanced visibility when scanning evaporators, hoses, fittings and seams.
• Useful for confirming even small hairline leaks that emit trace dye.
• Also handy for checking documents, labels and other fluorescent markings.

What materials and refrigerants is this kit compatible with?

The kit is built with heavy-duty brass connectors and an aluminum-alloy injector body so it stands up to repeated garage and roadside use. The detector electronics are calibrated for a wide range of halogenated refrigerants used in automotive and light commercial systems, making it versatile across R22, R134a, R404a, R410A and many blended refrigerants.

• Compatible with R22, R134a, R404a, R410A and most HFC/CFC/HCFC blends.
• Robust brass quick connectors for leak-free connections.
• Aluminum alloy syringe resists corrosion and wear.
• Probe and sensor suitable for cramped engine-bay access.

Who is this for? The Tellegloww kit is aimed at DIY mechanics, mobile technicians and fleet maintenance staff who need a portable, cost-effective method to detect, trace and visually confirm refrigerant leaks. If you service vehicle air conditioners, troubleshoot intermittent cooling loss, or want a compact kit for roadside diagnostics, this bundle gives the core tools to locate leaks and verify repairs quickly. Note: kit requires 4 AAA batteries (not included) and should be used following local refrigerant handling regulations.
