The SF6 Decomposition Product Analyzer is professional testing equipment for power system maintenance. It quantitatively detects characteristic decomposed gases including SO₂, H₂S and CO. These gases are produced when SF6 insulating gas has partial discharge or overheating faults inside GIS, circuit breakers and other high-voltage electrical equipment.
By analyzing the concentration of decomposition by-products, workers can accurately identify internal insulation defects and hidden faults in advance to remove safety risks and guarantee stable operation of substations. Featuring portable design, fast response and intuitive display, it is perfectly applicable to on-site field inspection for power stations.

FAQ for SF6 Decomposition Product Analyzer
Q1: What gases can this SF6 decomposition tester detect?
A: It can test SO₂, H₂S, CO within the range of 0~100 μL/L. HF detection (0~10 μL/L) is available as an optional configuration before purchase.
Q2: What is the sensitivity of the instrument?
A: The sensitivity for all measurable gases is ±0.1 μL/L, ensuring precise trace gas detection inside high-voltage equipment.
Q3: How long is the response time for gas measurement?
A: The response time is only 45 seconds. It has fast testing speed and nearly no preheating waiting time for on-site use.
Q4: Can the device automatically judge equipment faults?
A: Yes. It features an intelligent fault diagnosis system. According to the concentration data of SO₂ and H₂S, it automatically analyzes internal hidden faults and gives targeted maintenance suggestions.
Q5: Will ambient temperature affect the measurement results?
A: No. The measuring results are free from ambient temperature interference. Its working temperature ranges from -20℃ to +50℃, adapting to harsh outdoor substation environments.
Q6: What power supply modes does it support?
