Frequently asked questions
Go to help centerIt serves as an early-warning diagnostic tool. By tracking changes in gas concentrations (e.g., Acetylene), it detects latent thermal and electrical stresses. This allows for planned maintenance before a catastrophic equipment failure occurs.
It features a built-in high-resolution 24-bit AD circuit and industrial-grade chips. This ensures ultra-low noise levels and a stable baseline, allowing the equipment to accurately detect even trace components of dissolved gases with laboratory-level precision.
It turns “blind operation” into “informed maintenance.” Tracking gas trends (e.g., CO, H2) allows you to predict insulation degradation and thermal stresses. This proactive approach saves multi-million dollar assets from sudden fires and unplanned grid downtime.
