Pressure measurement

Differential pressure measurement on gas hot water heaters or on filters of air conditioning systems, and also flow measurements in ventilation ducts using a Pitot tube: the compact testo 510 differential pressure measuring instrument, which comes with a silicone connection hose and other useful accessories, can help you maintain and install systems in the sanitary and HVAC sector.

• Differential pressure measurement from 0 to 100 hPa 

• Flow measurement possible with a Pitot tube (available as an option)  

• Magnets on the rear allow hands-free work 

• 10 units to choose from, display in pascals can be selected 

With the Testo Smart Probes Heating set, you can measure and check all heating system temperatures and pressures in conjunction with your smartphone. The robust testo Smart Case enables the measuring instruments to be conveniently transported and ensures that they are always to hand when needed.

• Measurement of gas flow and static pressure

• Non-contact temperature measurement on underfloor heating systems and radiators

• Measurement menu for pressure drop test, including alerts via testo Smart Probes App

• Rapid image documentation with IR temperature readings and measuring spot marking

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

Professional pressure/leak detector for installation, maintenance and service of gas and water pipes. Specially designed to carry out reliable leak tightness checks, load tests, serviceability tests, temperature measurements in accordance with existing rules and regulations.

• Easy to set up, easy to use due to legally compliant measuring menus (i.e. according to TRGI 2008)

• Extremely accurate and DVGW-compliant measuring results

• Leak tightness checks of gas pipes according to TRGI 2008 and liquid gas pipes according to TRF 2012

• Easy to use due to automatic pressure build-up; quick and easy data storage

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
