The ECTHA-R Application is designed and developed by DRC, allowing you to record, quickly and in a digital format, rebound index values acquired from our test hammers directly on site.
Depending on the type of test hammer you are using, whether it is a mechanical or an electronic one (ECHTA-PRO, produced by DRC), you can use the app respectively in manual or automatic mode: in the first case, the data is entered directly by the operator using the keyboard; whereas in the second case, simply place the device near the electronic test hammer that you are using for the automatic recording of values via Bluetooth connection.
