Dräger P7-TDX

The professional device Dräger P7-TDX performs leak rate measurements at top speeds.

Without removing the gas meter, without determining the volume and without pressure boosting. Gas and liquefied petroleum gas lines can be measured up to 0.3 MPa (3 bar), and this all-rounder even measures water and waste water lines and tests regulators



Suitability for use per DVGW TRGI 2018

The Dräger P7-TD operates the leak rate measurements in best time – without removing the gas meter, without determining the volume and without pressure boosting. You only need to connect the single pipe connection with the gas valve for starting the measurement. A shiftable automatic start offers an important help for leaks at smaller plants with fast decrease of pressure.

Pressure monitor for monitoring of unusual pressure gradients

In the case of unusual pressure fluctuations of a plant the Dräger P7-TDX can measure and monitor it over a longer period. For this all pressure fluctuations which exceed freely adjustable limits, will be recorded for an evaluation.

Various applications

– Leak test according to TRGI 2018

– Leak testing with air on gas, liquefied petroleum gas and drinking water systems according to DVGW TRGI 2018,

TRF 2012, bulletin ZVSHK

– Leak testing for waste water lines per DIN 1610 und DIN 1986-30

– Leak testing with arbitrary pressure ranges, setting time and test time

– Loading test with air per DVGW TRGI 2018, TRF 2012, bulletin ZVSHK

– Drinking water system testing with water per DIN EN 806 with external high pressure sensor

– Regulator testing

– Pressure- and leak testing up to 0,3 MPa. Accuracy class 1 external high pressure sensors available for pressure

and leak testing up to 2.5 MPa.

Testing gas, liquefied petroleum gas and water lines

Versatile, quick and professional: In addition to testing gas and liquefied petroleum gas lines, the Dräger P7-TDX will also test water, waste water lines, regulators and pressure measurements up to 3 bar with air. Tests with water can be performed with an external sensor up 2.5 MPa.

Longterm measurements up to 48 hours

The Dräger P7-TDX is equipped with a precision pressure measurement process including temperature- and absolute pressure measurement, which provides testing times from 1 minute to 48 hours.

Built-in help function

The built-in operating instructions provide answers to questions concerning the device’s operation, these come in the form of instructions, suggested solutions and additional information.

Leak rate measurement at plants with large volume

The Dräger P7-TDX can also perform leak rate measurements at plants > 300 l.

Leak pretest

If there is no suitablility for use and official result needed the Dräger P7-TDX can also operate a shortened pretest. In this case the leak rate will be determined.


Measurements can be documented on site via IR printer or, if necessary, linked to customer or system data and the company logo and company address added via measurement report templates. The PC software with customer data management including import and export functions is considerably easier to use.

Shock and impact proof housing

The device features a shock and impact resistant housing which won’t let you down, even in rough conditions


The Dräger P7-TDX is equipped with Bluetooth LE as standard.

Access measurements anywhere, any time with the app Dräger mCon*

The app ensures ultimate mobility and instant access to all current measurement data. All data is transmitted straight from the analyzer to a smartphone or tablet via Bluetooth and is immediately available as a remote display. Measurements can be saved and sent by e-mail.

*App Dräger mCon on request.
