Testo 324 pressure gauge and leak detector
The testo 324 pressure gauge and gas leak detector allows for pressure measurements, DVGW-approved leak detection for all gas pipeline tests, tightness and maintenance checks.

The testo 324 pressure/leak detector can be used for the following applications
- Leak tightness checks on gas pipes (leak tightness check and load test according to TRGI 2008 and DVGW G 5952)
- Serviceability checks according to TRGI 2008 on gas pipes
- Pressure tests on water pipes (drinking water according to ZVSHK EN 806-4, waste water according to DIN EN 1610)
- Leak tightness checks on liquid gas pipes according to TRF 2012
- Gas pressure regulator inspections
- Pipe volume measurements
- Further applications including temperature measurements at radiators and pressure measurements at burners (die pressure, gas flow pressure…)
