À la recherche des fuites avec un détecteur de fuites
Une fuite peut avoir de graves conséquences sur de nombreux types de conduites. C’est pourquoi il est nécessaire de procéder aux contrôles requis avec un dispositif de mesure de pression adéquat afin d'améliorer la protection contre les erreurs et de satisfaire aux dispositions légales. Un détecteur de fuites Testo est le bon choix pour détecter rapidement les fuites.
Vous trouverez ici des appareils de mesure et de recherche fiables qui vous accompagneront idéalement au quotidien. Les manomètres et débitmètres de fuite sont contrôlés par la DVGW et déterminent automatiquement le volume des conduites de gaz. Des menus de mesure détaillés, structurés conformément aux directives prescrites, vous aident grandement dans ce cadre.
The following are some of the important measurements you can carry out with the leak detector:
- tightness test,
- load test,
- serciceabillity test.

When you detect leaks, the leakage meter enables a quick, precise check measurement. The gas leak detector has an integrated pump for this purpose. It quickly detects the gases present in the ambient air, such as methane and propane, and establishes the location of the gas leak. The gas concentration is shown in a simplified bar format on the display of the absolute pressure measuring instrument. If the limit values are exceeded, the instrument generates an alarm.
The absolute pressure measuring instrument is particularly handy in the pocket format. Just like the other reliable leak detectors, this one measures with an accuracy of +/-3 HPA. It also enables compensation of the absolute pressure to be tested in conjunction with flow measurements. If necessary, you can make an adjustment to the height above sea level to align the barometric air pressure. This means the measuring instrument can also carry out a precise barometric altitude measurement.
Leaks on natural gas pipes can be reliably detected with a gas leak detector. This is particularly important when hairline cracks or obsolete seals are to be expected.
Using a leak detector provides you with precise information that helps you both to establish the location and to determine the leakage rate.
Of course, you get the Testo instruments for leak detection along with all the relevant accessories, so that you are equipped with the complete package for pipework testing according to specifications:
- high pressure probe,
- high pressure connection,
- Y-distributor,
- system case with feed unit,
- if applicable, further accessories.
Fields of application and accessories for the leak detector
The innovative Testo pressure and leakage meters make user-oriented and reliable testing of gas and water pipes significantly easier. The refrigerant leak detector supports leak detection in the refrigeration technology field. This instrument quickly detects the most common refrigerants and also discovers tiny leaks. A compressed air leak detector works with an appropriate high pressure probe.
How to detect leaks – legal requirements and precision instruments
Testo's innovative leak detector has the seal of the mandatory DVGW test. You also get the necessary accessories for the pressure and leakage meter: system case, feed module, connector block, hose, test pump, adapter and other items. These enable you to carry out leakage measurements directly on the gas boiler. Typical applications for this kind of leak detector for gas pipe tests include:
- tightness and load test (according to TRGI 2008),
- serviceability test of the gas pipes,
- automatic determination of the pipe volume,
- LPG and waste water pipe test.
Leak detector and related test instruments
The beneficial features of Testo's leak detectors can be seen in their compliance with the specified directives and clear menu guidance. This makes it easy to carry out the required tests on the gas pipes and at other locations. The pressure and leakage meter carries out an automatic tightness test and thus saves you a great deal of effort.
The vacuum gauge also scores high marks with its great precision. The testo 552 digital vacuum gauge, which operates via Bluetooth, can for instance be used when a refrigeration system or a heat pump needs to be tested. This measures the pressure and automatically calculates the evaporation temperature. Its simple operation is supported by the practical single-hose connection and by the high-resolution, easy-to-read colour display. Furthermore, you can store the measurement data in a customer folder which has been previously set up and thus ensure clear organization of the documentation.
The high precision of the classic leak detector helps you with leak detection and with testing how serious the leak is. It is equipped with the following sensors for this:
- a flow rate sensor,
- an absolute pressure sensor,
- two differential pressure sensors.
