LF-301SF6 Quantitative Leak Detector (Replace Imported)

The SF6 high-sensitivity quantitative leak detector equipment, which replaces imports, is developed based on the principle of high-frequency magnetic field and low-voltage ionization. It includes one leak detection host, one set of detectors, and a maximum sensitivity of 0.01ppm. It can set a value alarm, and the alarm method is sound buzzer reminder and leakage point concentration change; Equipped with lithium batteries; The detector head is equipped with a PM1.0 filter to prevent micro dust from clogging the probe, which can effectively prevent instrument performance degradation; The sensor has no loss, a lifespan of up to 5-10 years, no radiation source, and is safe and reliable. Starting from 2020, a moisture removal correction module (patent number:) has been added, which can effectively prevent the concentration value of SF6 quantitative leak detector products from being affected by moisture during use, making the testing more accurate (optional). Table 1 Technical Parameters Table Project Technical Parameters Measurement Range (SF6) 0.01-500ppm (0.01-1000ppm, considering the best commonly used detection range, generally recommended 0.01-500ppm) Measurement Accuracy (highest sensitivity) 0.01ppm (v) 1.010-8 Equipment with or without radiation source No response time ≤ 10 seconds In 99.99% SF6 environment, 1 second, in 10% SF6 environment, the indication mode directly displays PPM and sound alarm
