The KDWG-II is a high-sensitivity handheld SF6 gas leak detector engineered for professional field use. It employs advanced infrared sensing technology to deliver fast, accurate detection of SF6 concentrations with a high pumping speed (≥800ml/min). The instrument features a user-friendly color LCD interface, one-key operation, and an integrated high-flow air pump for rapid sampling. With long battery life (≥5 hours of continuous use) and a rugged, portable design, it is ideal for on-site leak detection in power substations, electrical manufacturing plants, and SF6 circuit breaker maintenance scenarios.
