Leaks in a refrigeration system, such as an air conditioning system, can quickly have serious consequences. The system would no longer provide the required cooling capacity and, in the worst case scenario, the refrigeration system may even be damaged. The leak detectors from Testo can detect even the smallest leaks.

Testo is always working hard to develop the perfect measuring instrument for everything that can be measured as well.
"Be sure" – you can be sure – we promise you, and by this we do not just mean the precision of our vacuum gauges. But also that you will find exactly the right measuring instrument for you to deal with every measuring task in industry, research, technology and trade.
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.
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.
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.
Differential Pressure measurement is not everything.

Whether you are servicing a ventilation system, want to commission a heating system or are responsible for compliance with cleanroom regulations and filter systems – you will find your ideal solution for every requirement at Testo.
Pressure parameters play an important role in numerous applications in building services, industry and research. In order to ensure you have the right pressure measuring instrument to hand for every requirement, Testo offers you the appropriate instrument for each pressure.
Alongside differential pressure, absolute pressure is one of the commonly measured pressure parameters. Ensure the quality of your maintenance or servicing tasks with an absolute pressure meter from the market leader. This means you can be sure your values are right too. And at the same time take advantage of a first-class price-performance ratio.
Are you looking for a leak detector for fast and thorough leakage location? Testo's leak detectors are not only particularly accurate, they also recognize all common refrigerants. This means you are always perfectly equipped if there is the suspicion of a leak.
A Testo vacuum gauge enables you to handle all requirements involving the evacuation of refrigeration systems or heating pumps even more confidently. And if you don't just measure differential pressure, but wish to record other parameters too: a Testo digital manifold offers you numerous functions in just one instrument!
