Leakage measurement

The testo 312-3 pressure measuring instrument is your reliable partner when you want to test water or gas pipes. You can carry out load and tightness tests of gas pipes as well as pressure tests of water pipes using air with the testo 312-3 pressure measuring instrument.

• Load and tightness tests of gas pipes

• Pressure testing of water pipes using air

• Switchable measuring ranges with high resolution

• Alarm indicator for undershooting of freely adjustable limit values

The testo 312-2 pressure measuring instrument is suitable for carrying out pressure measurements when setting and maintaining gas heating systems. The pressure measuring instrument enables you to test the flue gas draught, the differential pressure of the combustion chamber in comparison to the surroundings, or the gas flow pressure, with a high resolution.

• DVGW-tested

• Switchable measuring ranges with high resolution

• Alarm indicator for undershooting of freely adjustable limit values

• Print out of measurement data with the testo fast printer

You can carry out all the necessary tests on gas heating systems as well as water and gas pipes with the testo 312-4 electronic differential pressure measuring instrument. Preset measuring processes, for example for load and tightness tests as well as serviceability testing on gas pipes, provide you with ideal support for your work.

• Tightness testing and load testing on gas pipes

• Serviceability testing with air by pressure drop on gas pipes

• Pressure testing on drinking water and waste water pipes using air

• Automatic recording of measuring values over several hours
