SNDWAY SW743A Refrigerant Leak Detector For Automotive
Check refrigerant and other gas leaks with the SNDWAY SW743A refrigerant leak detector. Its split universal flexible probe helps you reach different environments, while the MP-901 sensor provides high sensitivity and a response time of less than 10 seconds. The LCD shows sensor concentration, battery charge, concentration unit, and temperature. Automatic backlighting supports viewing the display, while sound, LED, and vibration alarms provide real-time feedback. A higher beep frequency indicates a higher concentration. Flexible detection: Diffusion sampling helps the probe detect gases in air. Adjustable alarms: Set low-alarm and high-alarm functions. Reduced interference: An air filter helps reduce disturbance from water, air, and dust. Portable design: The detector uses high-strength ABS engineering plastics and weighs about 200 g. Use it for air-conditioning, refrigeration systems, and refrigerant recovery equipment. It also detects halogen gases, ethylene oxide, ethanol gas, and Halon gas. Specifications Brand and model: SNDWAY SW743A Detection gases: CFCs including R11, R12, R500, and R503; HCFCs including R22, R123, R124, and R502; refrigerants including R134a, R404a, and R125 Measurement range: 0–1000 ppm Resolution: 1 ppm Operating voltage: DC 4.5 V Power: 3 × AAA alkaline dry cells, not included Run time: More than 6 hours Warm-up time: 30 seconds Response time: Less than 10 seconds Display: LCD with automatic backlighting Alarm: Sound, LED, vibration, and low-voltage indication Service temperature: −10 to 50°C Size: 156 × 64 × 27 mm Weight: About 200 g Sensor: MP-901 metal oxide semiconductor gas sensor Packaging Package weight: 0.30 kg / 0.67 lb Package size: 18 × 8 × 4 cm / 7.09 × 3.15 × 1.57 in Quantity per carton: 98 pieces Carton weight: 30.00 kg / 66.14 lb Carton size: 50 × 50 × 60 cm / 19.69 × 19.69 × 23.62 in This detector is designed for real-time refrigerant and gas leak testing in automotive, air-conditioning, and refrigeration applications.
