Product OverviewThe Smart Sensor AS5750L is a professional, handheld electronic leak detector engineered to quickly and accurately identify leaks in various refrigeration and air conditioning systems. Designed for HVAC technicians, refrigeration contractors, and maintenance engineers, this device uses a high-sensitivity semiconductor sensor to detect all halogen-based refrigerants, including CFCs, HCFCs, and HFCs (such as R134a, R404A, R22, and R410A). Its compact, ergonomic design and flexible stainless steel probe make it ideal for inspecting confined spaces, valves, pipe joints, and evaporator coils where leaks commonly occur. Key Features High Sensitivity: Capable of detecting leaks at rates of less than 0.5 oz/year, allowing for the identification of even minute punctures before they escalate into major system failures. Rapid Response: Features instantaneous response times and a quick warm-up period (typically under 20 seconds), ensuring efficiency during field service. Intelligent Alert System: Equipped with both audible alarms (which increase in frequency near a leak) and visual LED indicators to provide clear, real-time feedback on leak intensity. Adjustable Performance: Includes sensitivity adjustment settings to optimize detection based on the specific environment and the size of the leak. Portable & Durable: Built with a lightweight, ergonomic chassis and a flexible probe, making it convenient for daily use in diverse industrial and residential cooling environments.
