Product Description
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.
These measurements are possible with the testo 312-4 differential pressure measuring instrument
- 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 our
high-pressure probe (can be ordered as an option)
- Pressure testing on drinking water pipes using water and with the support of
the optional 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 our high-pressure probe (can be
ordered as an option)
- 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
Practical features of the differential pressure measuring instrument
The testo 312-4 differential 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 testo fast printer, which can
be ordered as an extra, 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 measuring
instrument (e.g. high-pressure probe or thermocouple probe for temperature
measurement).
