• Key Specs: 25–2000 ppm range; fuel-cell sensor; valve-mount design
• Condition: New Original (New Surplus), not refurbished

Key Selling Points & Differentiators

• Dynamic oil sampling through one valve eliminates external pumps and tubing, reducing installation time and leak points compared with multi-port systems.
• Composite sensor covers the main failure modes (H₂ general fault, CO paper overheating, acetylene arcing, ethylene oil overheating) while the optional H₂-only version focuses strictly on hydrogen.
• Incoming inspection verifies packaging, labels and enclosure integrity. Functional checks include power-up self-test, LCD verification, communication port handshake and basic sensor response confirmation where a test stand is available. Final packaging uses protective covers, sealed bag and carton with dated QC label. Test report can be supplied. Passed the above checks; verified functional at time of test.
• Clear alternative to full multi-gas online monitors when the application only requires an early-warning composite or hydrogen trend; not recommended as the sole monitor for the most critical EHV transformers that demand complete dissolved-gas profiles.
• Automatic self-test every 15 days and service-alarm relays support predictive maintenance without constant site visits.
