Product Introduction: The SF6 laser leak detection system is a device based on the advanced photoacoustic gas detection principle, with a detection range as low as 6 ppb, exhibiting extremely low cross-sensitivity and long-term stability. It accurately measures the concentration of SF6 by utilizing the sound waves generated through the interaction between laser pulses and SF6 molecules. The system comprises a measurement unit, laser, vacuum pump, and controller, and it is operated through a custom control software running on a Windows system. Its features include high sensitivity, no radiation, no need for pure argon assistance, insensitivity to temperature and humidity, and continuous self-diagnostic capabilities. The system performs fully automatic measurements and data storage, meets multiple international standards, is portable and rugged, suitable for SF6 leak detection under various environmental conditions, providing strong support for industrial safety.
