testo 312-4

Productdescription

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.

    • Gas-tightness and serviceability test by pressure drop on gas pipes according to DVGW-TRGI 2008• Load test on gas pipes according to DVGW-TRGI 2008 with the help of the high pressure probe• Checking the regulator by recording the measurement values over a defined period• Checking the gas connection pressure and gas flow pressure as well as setting the jet pressure on gas burners and boilers• Pressure tests on drinking water pipes with water using the high-pressure probe according to DIN 1988 (TRWI) as well as with air accoding to the ZVSHK information sheet• Pressure test on waste water pipes according to DIN EN 1610
