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.
Tightness and serviceability testing by pressure drop on gas pipes in accordance with DVGW TRGI 2008
Load testing on gas pipes in accordance with DVGW-TRGI 2008 using the included high-pressure probe
Pressure testing on drinking water pipes using water and with the support of the included high-pressure probe in accordance with DIN 1988 (TRWI) and using air in accordance with the ZVSHK information sheet
Pressure testing on waste water pipes using the included high-pressure probe
Checking the gas pressure regulator by recording the readings over a defined period (max. 25,000 readings)
Checking the gas connection and gas flow pressure, as well as setting the nozzle pressure on gas burners and boilers
The testo 312-4 pressure measuring instrument offers a high level of operating convenience in order for you to carry out pressure measurement efficiently - for instance through preset measuring processes or the clear presentation of readings on the large display. The included testo fast printer means you can produce measurement data printouts directly on site. The easyheat PC software is available to you as an option for data transfer and evaluation. Furthermore, probes which are also available for various measuring tasks can be attached to the differential pressure meter (e.g. high-pressure probe or thermocouple probe for temperature measurement).
