A measuring instrument for carrying out all necessary tests on gas heaters and pipes as well as water pipes. Inherently safe thanks to the use of C-Flex hoses with high impermeability. Legally compliant measurement procedure for pre-test, main test and leakage quantity measurement on gas pipes. Recording of measurement values over a defined period (e.g. 24 h) and data transfer and analysis on PC software incl. graphic presentation.

Features:
- Tightness testing and load testing on gas pipes
- Serviceability testing with air by pressure drop on gas pipes
- Pressure testing on drinking water and waste water pipes using air
- Automatic recording of measuring values over several hours
