Over time, gas and water systems may develop leaks, necessitating regular checks for safety and tightness in compliance with DVGW, ÖVGW, and UNI regulations. The Testo 324 facilitates precise load, tightness, and serviceability tests, ensuring proper functionality of pipes and valves, especially during adjustments or significant changes. This digital measuring instrument features advanced sensors for accuracy and combines all necessary elements in one convenient case. By introducing gas into the system, the risk of dangerous gas-air mixtures is minimized. DVGW-G-5952 tested for reliability.
