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 our App for your smart phone or tablet – 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.
