Use the testo 312-2 fine pressure measuring instrument to
check flue gas draught, differential pressure in
the combustion chamber compared with ambient pressure
or gas flow pressure with high
resolution. Fine pressures with a resolution of 0.01 hPa can
be measured in the range from 0 to 40 hPa.
DVGW approval according to TRGI for pressure settings
and pressure tests on a gas boiler.
The versatile pressure measuring instrument testo 312-3
supports load and gas-rightness tests on gas and water
pipelines up to 6000 hPa (6 bar) quickly and reliably.
Everything you need to inspect gas and water pipe
installations: with the electronic pressure measuring
instrument testo 312-3, pressure- and gas-tightness can be
tested. Via pressure drop, you can quickly determine the
amount of gas leaking and the serviceability of the gas
pipelines. A gas leak is quickly detected by testo 316-1.
