Practical test P7-TDX

Measuring without compromise:
Why the P7-TDX does its job more successfully.

Working with gas involves dangers. That´s why users need instruments that are easy to control like an extended arm and that are absolutely reliable like a good colleague. And, of course, always working fully functional. Like out Dräger P7-TDX for pressure, tightness and leak rate measurements. Tim Gleiß, owner of Heizung Sanitär Gleiß in Herdecke, Germany, has tested our new device and tells us why it is a real guarantor of success.

Editior: Mr. Gleiß, what is your daily work routing? Where are your priorities?

Tim Gleiß: Mainly I carry out tests on gas installations. The regular maintenance by a specialist is in my opinion extremely important, because damage to gas pipes are often often not visible for laypersons. The gas safety check helps to detect deficiencies early on. That´s also in the interests of my customers. Precise measurements can avoid repair costs and prevent dangers for people and the environment. With regular maintenance and security checks you´re always on the safe side – and with the P7-TDX this is done quickly and reliably.

What makes a good pressure and leak test device gauge for you? And what criteria does the P7-TDX meet?

Tim Gleiß: Of course: the simple operation. A device must be intuitive to use – I don´t want to read through pages of a manual. An I that point, of course, the P7-TDX convinced me. The menu structure is simple and self-explanatory. The touchscreen gives me a clear overview and allows me the fast control. The robust device is very good in the hand and holds out pretty well – just right for the craft.
It is also important that the device is DVGW approved. For the P7-TDX I know 100% that all regulations are met. Because I can perform many different measurments with only one device – so pressure, tightness and load testings – it´s of course much faster in everyday life. And the device works almost independently which saves a lot of time.

Editor: The Dräger P7-TDX is very flexible in use and offers many highlights. What else makes the device special for you?

Tim Gleiß: There ary many additional features. Especially great is the pressure monitor. This makes troubleshooting in case of sporadic pressure flurctuations much easier than using a long-term measurement. At the end of the measurement I get all events accurately reported when pressure fluctuations have occurred. I do not have that with a long-term measurement. Another plus is the leak pre-test. I can quickly see if there is a leak or not before I have to to a complete usability test. This saves a lot of time. Extremely practical are also the four connections for external sensors. I can connect the 25 bar sensor and easily check water pipes. This is genius!

Editor: How important are the acquisition costs for a new pressure and leak tester?

Tim Gleiß: When it comes to buying, the quality, user-friendliness and reliability of the new measuring device are of primary importance to me. Of course, the price-performance rationmust be right, but I don´t want to save in the wrong place. Because: What´s the use of a cheaper pressure device if I can´t do all measurements I need? Or if it´s possibly not approved? That´s out of the question for me. Everything is right with the P7-TDX – price and performance. And the investment even pays off, after all, I can still save costs with this device. Since it works almost by itself and especially fast, I can carry out more measurements during the day than before and also carry out gas safety checks in the shortest possible time. So I have no real overhead, save a lot of time in everyday life and earn more money. Along with the added features, the device does everything I need to work more effortlessly and cost-effectively.

Editor: The documentation of the measurement results becoming increasingly important nowadays, especially in the case of damage. How important is it to you?

Tim Gleiß: The documentation is very important to me. Especially in case of damage, I can quickly prove that everything was properly checked. Thanks to Drägers PC software, measurments protocols are easily created. For my documents but also as a delivery to my customers. That means more safety for both sides.

Dräger FG4200 and Dräger P4000

Twice as great

The best devices for any application – expect nothing less from Dräger. And the new FG4200 and the P4000 are the perfect offer straight from the start.


Dräger FG4200 für die Abgasmessung

Dräger FG4200

The different functions have been redesigned on the FG4200 and all steps aligned even more efficiently. Incorporating requests from the trade, the new for flue gas analyser is extremely compact and one of the smallest and lightest devices on the market. Merely 20 cm long and weighing only 258 g, it’s the ideal companion for any service and maintenance task. The proven Dräger measurement precision and intuitive handling make the FG4200 perfect to work with. The powerful Li-Ion rechargeable batteries ensure an even longer runtime.

Dräger P4000

The P4000 in turn is the first thinking pressure tester. It features various measuring programs with default parameters for common tests. The P4000 also features an incredibly light weight and a slim design. The colour touch screen ensures intuitive device operation. Scrolling up and down makes the menu particularly easy for the user to navigate. The alphanumeric input allows you to record promptly names and values without complex navigation.

Quickly ticked with the Dräger P7-TS


With the patented MSI comparison leak rate method, suitability testing is quickly ticked. Leak rate measurement is completely accurately and extremely quick. Without removing the gas meter, without determining the volume and without pressure boosting. Simply connect the single hose connection to the gas fitting, start the measurement process, finished! So you can offer suitability testing as part of servicing without adding complexity.

Tough - Dräger EM200plus


The Dräger EM200plus is just as reliable as the rest of the Dräger EM200 series, even in rough conditions. Equipped with shock and impact resistant housing.

In addition to maintenance and service on gas, oil and solid fuel furnaces, the Dräger EM200plus will perform TÜV-certified averaging measurement. Suitability testing to TRGI 2018 is also semi-automatic.
