Description
We make pressure tests on gas and water pipes smart
„The smart memo marks a evolutionary technical leap towards completely new functions and possibilities that the new pressure measuring system offers and will offer.” Bernd Esders
We take the lead!
Handle the same task and save time with the smart memo! Because time is money! The new smart memo pressure measuring system offers many advantages over its predecessor.
By connecting several intelligent, interlinkable sensors, it is possible to simultaneously measure and document temperatures with high precision via the ground spike
and contact sensor. The new smart function “Dynamic Pressure Test” automatically allows optimised pressure tests during the adjustment time with significant time savings.
Compatible with a multitude of intelligent external pressure sensors, it enables all pressure tests according to DVGW G 469 and W 400 (DIN EN 805) with only one device.
Users can equip the smart memo with the software and sensors they need as required. Later required updates, functions and test sequences are simply downloaded online.
The big advantage for you is that the upgrade can be carried out completely automatically from your desktop.

Simplified data transmission - improved connectivity
With the integrated mobile technology, test protocols including legally binding signatures can be transmitted quickly and
error-free by email or uploaded to the Esders live cloud. Location data can be automatically stored in the inspection report
via GPS. The costs for the transmission of an inspection report are calculated transparently per measurement and are lower
than the previous costs for printouts with a printer. A paper document can still be printed out using the Bluetooth interface.
Dynamic Pressure Testing – What does that mean?
That is an intelligent new function. The Dynamic Pressure Test either saves time when less adaptation time is required, or it increases the
chance of passing the test when the recommended adaptation time is not sufficient. The Dynamic Pressure Test is a newly developed,
smart function that you can use for the first time in our smart memo. It provides you with maximum support in your daily work.
It will soon also be available for the German B3 test service line G 459-I and the B3 test supply line G 469.
Data management
It was not so long ago that printing on thermal paper was a revolution on the construction site.
As an environmentally conscious and future-oriented company, we want to do without paper and at the
same time make your everyday work easier.
With Esders Connect the measurement data will directly be send to your office via integrated LTE
– fast, paperless, digitally and DSGVO compliant. You have the option of specifying up to three e-mail addresses in order
to send the completed test reports to them. The recipients also receive the GPS data for the exact localisation of the
measurement. The administration is clear and can be accessed from anywhere at any time.
Esders Connect is browser-based, so no updates are required and you always have the latest version available.

ZTV TKNetz 40
Additional Technical Terms of Contract of Telekom for construction works on the telecommunications network Part 40
Due to the expansion of the fibre optic network, the tightness test of the cable protection pipes (speed pipes), into which the fibre optic
cables are later blown, is subject to mandatory recording. The test procedure is specified by the Telekom and written down in the ZTV TKNetz 40.
For our smart memo, we have included the "Option ZTV TKNetz 40" for tightness testing of empty conduits when laying fibre optic cables.
The accessories required for carrying out the test are also available.
For further questions, please contact your responsible partner or our internal sales team. We will provide further information and answer your questions.
