Refrigerant Leak Detector, Aprvtio ALD-200 3-in-1 Freon Leak Detector Tester A3 A2L A1 Refrigerants Compatible, Rechargeable, Multipule Alarm, Heated Diode Sensor for HVAC R32 R454B R410A R134A R290

【Aprvtio Upgraded Sensor & 3-in-1 Detection】 Equipped with the aprvtio next-generation heat diode sensor, this ac leak detector goes beyond traditional units to accurately locate leaks in A1 (R410A), A2L (R32, R454B), A3 (R290, R600) refrigerants and other gases such as H2/N2 tracer gas—covering all types with true 3-in-1 detection capability.

【High Sensitivity & Micro Leak Detection】 With sensitivity adjustable up to 0.14 oz./yr., leak detector hvac quickly pinpoints even the smallest micro leaks that soap bubbles or dye tests often miss, saving hours of troubleshooting.

【Audible & Visual Alarms with Mute】 As a reliable hvac leak detector, the refrigerant leak detector hvac provides a clear 2.8-inch TFT color display showing concentration levels, while the beep frequency increases as the leak intensifies. The mute button allows quiet operation when needed.

【2.8-inch TFT Color Display】The detector de fugas de refrigerante is equipped with an advanced color graphic display, this R134a leak detector ensures optimal visibility and readability in both low-light conditions such as basements and brightly lit outdoor environments.

【Smart Functional Capabilities】Intelligent features including Peak Mode (captures the maximum leakage reading) and Reset Function (minimizes false alarms by recalibrating the sensor) make this R290 leak detector a user-friendly and reliable tool for HVAC professionals.

【Durable, Oil-Resistant & Field-Ready】 The freon sniffer is built with an oil-resistant and impact-resistant housing, this freon sniffer withstands harsh job site conditions. The rechargeable battery supports a full day of service, making it ready whenever you are.

【Easy Setup & Accurate Calibration】Designed for ease of use: fully charge before first use, warm up the sensor, and perform auto-zero calibration in clean air. The Peak Mode and Reset Function of the hvac tools help reduce false alarms, ensuring consistent and accurate readings every time.

【Professional HVAC & DIY Ready】Trusted by HVAC technicians, maintenance professionals, and DIY enthusiasts, the ALD-200 r454b leak detector is ideal for quick leak detection on heat pumps, air conditioners, refrigeration units, and automotive A/C systems. Detects leaks with precision comparable to high-end detectors at a fraction of the cost.
