A Testo manifold can do virtually anything that is required for the commissioning, servicing and maintenance of heat pumps, air conditioning and refrigeration systems. You will have numerous functions in a pleasingly compact and robust instrument. Testo's manifolds measure temperatures, calculate superheating or subcooling, take on temperature-compensated leakage testing for you and help you to measure vacuum. The process is even smarter: because your manifold sends all the data via Bluetooth to the practical testo Refrigeration App which you have installed on your smartphone or tablet. Measuring today's way. At least with Testo.

If there is the risk of a leak, you have to act quickly, so that you can immediately stop any substances that are aggressive or harmful to health which might be escaping. You need a fast and clever instrument for leak detection. The best solution is a Testo leak detector which combines both features. And what's more is also high-precision, recognizes all common refrigerants and is easy to handle even in difficult-to-access measurement environments. However, not in a vacuum. There, you should resort to a vacuum gauge again.

The pressure sensor makes the difference: it has to be the right one, not only for the measuring values to be highly precise, but also for them to suit your task. For absolute pressure measurement, it has proved to be advantageous to rely on an absolute pressure meter from the market leader Testo. Testo not only offers you ultimate quality, but also an ultimate price-performance ratio. That is unbeatable. Testo also plays in the Champions League when it comes to the differential pressure gauge segment. Choose your ideal pressure measuring instrument from a large range of top products and accessories.

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.

With a gas leak detector from Testo, you detect leakage from gas pipes quickly, safely and norm-compliantly.

• Fast reaction to even the smallest gas quantities

• Flexible probe reaches even the most difficult-to-access places; audible and optical alarm as soon as a leak is detected

• Additionally: Measuring instruments for tightness testing, load testing and serviceability testing

Good indoor climate depends on the carbon dioxide content of the air. With a Testo CO₂ measuring instrument you take the first step towards a pleasant indoor climate.₂ Messgerät machen Sie den ersten Schritt zum Wohlfühlklima.

• Monitoring and optimizing indoor climate

• Multifunction instruments for CO₂, humidity, lux, degree of turbulence and more

• CO measuring instruments for monitoring and measuring CO in boiler rooms

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!
