Gas tightness testing is the most critical safety check for gas appliances. A gas tightness testing machine pressurizes the gas circuit and detects any pressure drop that would indicate a leak.

Why It Matters

A single leaking gas valve can cause serious accidents. Standards such as EN 30 (gas stoves) and EN 26 (water heaters) require 100% tightness verification before products leave the factory.

Key Features to Look For

  • High-precision pressure sensors with 0.5 class accuracy
  • Automatic pass/fail judgment and traceable records
  • Multiple test stations for production line throughput
  • PLC + HMI control for easy operation

Wanhe Testing designs gas tightness machines integrated into complete gas appliance test benches for factories and laboratories.
