Elitech WJL-6000S Refrigerant Halogen Leak Detector – HVAC Diagnostic Tool for Freon R134a, R410a, R22 & More
The WJL-6000S is a high-sensitivity corona discharge halogen leak detector designed specifically for locating refrigerant leaks. It works with virtually all common refrigerants, including R134a, R410a, R22, R404A, R1234yf, and other CFC/HCFC/HFC/HFO blends. Featuring 7 adjustable sensitivity levels, both audible and visual alarms, and a flexible 7.9-inch probe that reaches tight spaces, this detector is an essential tool for HVAC technicians, refrigeration service professionals, and automotive AC repair.
⚡ Concentration & Battery Indicator
- As leak concentration rises, beep frequency increases and up to five LEDs illuminate sequentially.
- The first LED doubles as a battery alert: solid green = normal, flashing orange = low voltage (replace batteries soon).
🔬 Advanced Corona Sensor
- Responds to all halogen-based refrigerants: CFCs (R12, R11, R500…), HCFCs (R123, R124, R502…), HFCs (R134a, R404A, R125, R1234yf…), and blends like AZ-50, HP62, MP39.
🎚️ 7 Sensitivity Levels
- Choose from 1 (low) to 7 (high) to match the leak size – max sensitivity 0.21 oz/yr (6 g/yr).
- Startup tone: 2 beeps/sec; leak alarm: 10 beeps/sec.
- Higher settings detect smaller leaks with precision.
🚨 Audible & Visual Alarms
- LED flash rate and beep speed increase with leak concentration.
- Dual‑color battery LED: green (good), orange (replace soon).
🌀 7.9" Flexible Probe
- Bends easily to access evaporator coils, compressor backs, and other confined areas.
- Replaceable sensor tip extends detector life and maintains accuracy.
🔋 4×AAA Battery Powered
- Ultra‑low power consumption – up to 50 hours continuous use.
- Comes with a black zippered carry pouch for convenient storage and portability.
- * Batteries are NOT included

🧰 Professional Usage Tips
• Leak areas are often coated with oil or dirt – keep the sensor tip clean to avoid false alarms.
• Avoid moisture or solvent exposure on the sensor tip.
• When testing R134a, R410a, or R22 systems, start at a lower sensitivity and increase gradually to pinpoint tiny leaks.
• If the detector hasn’t been used for a while, install fresh batteries and allow a 6‑second warm‑up before starting.
❓ Frequently Asked Questions
Q: Is it normal for the device to start beeping when turned on?
A: Yes, it beeps upon powering on to indicate startup. When a leak is detected, the alarm sound becomes more urgent (frequency increases).
Q: Why does the product alarm when not in a leaking environment?
A: Possible causes:
1. Probe blockage – clean according to the manual.
2. Probe damaged – replace it.
3. Circuit board damage. Additionally, temperature changes can affect the sensor's behavior; allow the detector to stabilize in the working environment.
Q: Why does the product fail to power on?
A: Common reasons:
1. This product does not include batteries – install 4 fresh AAA batteries before use.
2. Poor contact in the battery compartment – check and clean contacts.
3. Knob switch damaged – please contact customer support.
