RA-912F SF₆ Gas Analyzer with Pump-Back System

The RA-912F is a high-performance, portable SF₆ gas analyzer designed to measure gas purity, moisture, and decomposition by-products such as SO₂, H₂S, and CO with precision and reliability. Engineered for field use, this unit features a built-in gas pump-back system that enables zero-emission testing by recovering and refilling SF₆ gas back into the system or external storage, making it a vital tool for power utilities, substation maintenance teams, and gas monitoring professionals.


Key Features & Benefits

All-in-One Gas Measurement – Accurately measures SF₆ gas purity, moisture content, and decomposition gases (SO₂, H₂S, CO) to ensure the integrity of gas-insulated equipment.

Zero Emission System – Built-in pump-back technology allows full gas recovery, reducing environmental impact and minimizing gas loss.

Large 10.4” Touch Screen – Intuitive touchscreen interface combined with physical key input for flexible, user-friendly operation.

One-Key Automatic Testing – Simplifies operation with automated test sequences and real-time data locking.

Expert Diagnostic Function – Evaluates results against predefined standards to provide pass/fail guidance.

Modular & Maintainable – Proprietary design supports sensor replacement and module-level repairs for extended life and low maintenance.

USB Data Export & Storage – Stores large volumes of test data with easy export via USB.

Rugged Field Design – Housed in a waterproof, dustproof, and shockproof IP67-rated trolley case with wheels for portability.

Long Battery Life – High-capacity 5200 mAh rechargeable battery supports multiple tests on a single charge.
