Frequently asked questions
Go to help centerIt utilizes long-life precision sensors to detect trace decomposition gases like H2S, SO2, HF, and CO. Combined with a large touch screen for real-time curve display, it delivers lab-grade accuracy directly in the field.Uniquely, it allows users to perform calibration on-site, ensuring data reliability without sending the unit back to the factory frequently.
It acts as a diagnostic doctor for GIS equipment. By precisely measuring Trace Moisture (Dew Point) and Decomposition Products (SO2, H2S), it identifies insulation degradation and internal arcing faults at an early stage, preventing catastrophic short circuits.
Yes. It is designed with High-Integrity Sealing Joints and precise Micro-Flow Control (0.2~0.6L/min). This closed-loop system strictly prevents the leakage of toxic decomposition gases (like HF and H2S), fully protecting the operator from hazardous exposure.
They offer superior Chemical Resistance. When testing faulted equipment containing corrosive by-products like HF and SO2, standard sensors often fail. Our durable components withstand these harsh chemicals, ensuring reliable detection even in the most severe breakdown scenarios.
