The MSV Mini STT Electronic Tension Measuring Device is an easy-to-use and handy little machine that measures the pressure on the strings.

The MSV Mini STT helps you decide when to put on a new string and is a must for all professional stringers and ambitious tennis players.

How to:

Measure the pressure on your newly strung rack. The MSV MINI STT then stores the value. After e.g. 10 hours of play, measure again for the current value. Compare this with the stored value, which is displayed after you have pressed the MEMO button. If the difference is more than two kilograms, you should consider a new stringing.

Important to know: The string bed tension measured by the MSV MINI STT (as well as all other string bed tension meters) is not directly comparable to the reference values of the stringing machines. The Mini STT is therefore not suitable for checking whether a racket is correctly strung. And a tension loss of up to 15% immediately after stringing and another 15% after the first game is quite normal. There are some tennis rackets with frame characteristics that make accurate measurement difficult or impossible.

How does the MSV MINI STT work?

You attach the MSV MINI STT to the string bed. By tapping the frame with your finger, you make the stringbed vibrate. The resonance frequency gives the tension pressure. This is displayed digitally exactly in kiloponds (almost exactly equivalent to kilograms). Measurement range from 17 to 35 Kp (37 lbs to 77 lbs).

2 button cell batteries (1.5 volts) provide approximately 4,000 measurements or cover a 16 month period. The unit is always on. That's why we put the batteries in just before shipping.


Dunlop Slazenger confirms the reliability of the Mini STT.

I serve 60 times a day with ServeMaster and have noticed an improvement in just a few weeks. Yesterday I played a match and felt so confident when I served.
