Top Selling Points & Product Advantages (Keyword Focused)

1 Touch Screen + Wireless Computer Dual Control System

The steel fire retardant coating test furnace supports standalone touch screen operation without extra PC software installation; built-in wireless communication module realizes remote control. One computer can synchronously control multiple GTL-50 furnaces, and one furnace can receive multi-terminal monitoring, greatly improving lab batch testing efficiency for fireproof coating inspection.

2 Full-Automatic Unattended Fire Test Workflow

1. Automatic spray diesel ignition & auto re-ignition when flame extinguishes during high-temperature testing
2. Auto stop heating once preset fire resistance time/temperature is reached
3. Real-time automatic plotting of furnace temperature curve & furnace pressure curve
4. Automatic exhaust air and forced cooling after test completion
5. Auto screen identification & elimination of faulty thermocouple signals, avoiding invalid test data
6. Anti-power-off protection design: test data auto saved, equipment protected from sudden power failure damage

3 Ultra-High Testing Precision, Error Lower Than National Standard

Adopts Class II nickel-chromium/nickel-silicon K-type sheathed thermocouples, dual monitoring of furnace internal temperature and specimen back unexposed surface temperature. Users can choose average back temperature or single-point temperature for control, all temperature deviation indexes are superior to GB14907-2018 standard limits, ensuring authoritative, audit-ready test reports for fire retardant coating certification.

4 Large Data Storage & Traceable Test Records

Built-in large-capacity memory supports storage of more than 100 groups of complete test data, including temperature curves, pressure records, timing logs and coating insulation index data. All historical test files can be exported for third-party certification audit, ideal for fire coating factory QC labs and accredited testing institutions.

5 Integrated Mobile Compact Furnace Cabinet

All-in-one 1.6m cubic furnace body with bottom moving casters, easy to transport and place in small fire test labs. Fully automatic spray heating system with stable diesel combustion, uniform furnace temperature field, no local overheating affecting steel fire coating test results.

Wide Application Scenarios

• Steel structure fire retardant coating manufacturers daily quality inspection
• Intumescent fireproof coating & thin/thick type fire coating R&D laboratories
• ISO 17025 accredited construction fire safety testing laboratories
• Architectural design institutes and building material supervision departments
• Fire protection engineering companies for coating performance verification
• University fire engineering material research labs
