Refrigerant Leak Detector, Aprvtio WJL-6000PRO 3-in-1 A2L Freon Leak Detector Rechargeable, 0.14 oz/yr Sensitivity, Audible & Visual Alarms, Automotive AC Leak Detector for R454B R1234yf R32 R410A

【Dual Detection Modes: PPM + %LEL for Precision & Safety】 This gas leak detection kit measures refrigerant leaks in two ways-PPM for ultra-sensitive micro leak detection, and %LEL for monitoring A2L refrigerant safety-giving you professional-grade diagnostic power in one versatile tool. 【Upgraded All-Metal Probe for Durability】 The all-metal, dirt-proof, wear-resistant probe on this refrigerant leak detector hvac is built to withstand tough job site conditions-no more broken plastic tips, just reliable performance day after day. 【Audible & Visual Alarms with Mute Function】 When a leak is detected, the digital display of the halogen leak detector shows the reading and the audible tone changes to a siren. Press the MUTE button to turn the buzzer on or off-ideal for quiet indoor environments where you need to focus. 【Ultra-Fast Response & Accurate Identification】 Time is money when you’re on the job. This r454b leak detector responds to refrigerant gases in just 2 seconds, with precise refrigerant identification within 10 seconds-helping you diagnose problems faster and move on to the next service call. 【Full Coverage: Traditional & A2L Refrigerants】This hvac leak detector detects a full spectrum of gases including: [CFCs: R11, R12, R13, R113, R114, R115, R500, R502, R503] [HCFCs: R22, R123, R124, R141b, R142b, R401A, R401B, R402A, R402B, R408A, R409A] [HFCs: R32, R125, R134a, R143a, R152a, R404A, R407C, R410A, R410B, R417A, R422D, R427A, R438A, R448A, R449A, R452B, R453A, R507] [HFOs: R1234yf, R1234ze(E), R1233zd(E), R1336mzz(Z), R514A, R1224yd(Z), R1243zf] [Blends: R401A, R404A, R407C, R410A, R507, AZ-50 (R507), HP62 (R404A), MP39 (R401A), NU-22 (R422D)] [PFC: PFC-14, PFC-116, PFC-218, etc] [HCs(Hydrocarbon): R50, R290, R600a etc.][5%hydrogen/95% nitrogen Racer Gas] 【Auto Calibration for Stable, Accurate Readings】 Power on this a2l refrigerant detector in a clean, fresh air environment, and it performs a short auto-calibration warm-up to ensure stable PPM and %LEL readings-reducing false alarms and giving you confidence in every test. 【1800mAh Rechargeable Battery for All-Day Use】 Powered by an 1800mAh rechargeable battery, this car ac leak detector kit provides over 20 hours of operation. No disposable batteries needed-just use Type-C cable to charge and you’re back on the job. 【Adjustable Sensitivity to Prevent False Alarms】Fine-tune detection levels of the R290 leak detector to match your working environment. Lower sensitivity in high-concentration areas for precise pinpointing of refrigerant leaks without constant triggering. 【Ideal for HVAC Service & Home】The hvac tools is perfect for detecting leaks in R410A, R454B, R134a.Suitable for HVAC technicians, auto mechanics, RV owners, and homeowners checking car and home AC systems., Manufacturer: Aprvtio
