ERT300 TENSION CONTROLLER

The ERT 300 system is the reference tool for players who want to know the tension of their strings.

Indeed, thanks to micro-impulses the ERT 300 can determine the dynamic tension of your string, which you can then convert into kilograms to get the tension of your racquet.

This tool is the most used by professional stringers on the circuit.

Very simple to use, the ERT 300 must be positioned on the three widest strings of the crosses thanks to its small claws.

The device will then send micro-impulses to determine the dynamic tension of the string, this value is expressed in DT.

Thanks to the table provided, you can easily convert this data into kilograms or pounds.
