Description
TESTO 312-4 Differential pressure measuring instrument
Order-Nr. 0632 0327
A variety of directives describe the tests which have to be carried out before commissioning water and gas pipes. The testo 312-4 differential pressure measuring instrument offers measuring processes for load and tightness tests as well as serviceability tests on gas pipes using air. It also enables the checking of static gas and gas flow pressures, as well as the nozzle pressure setting on gas burners or boilers.
