Surtronic Duo

Portable rougness testers for checking surface roughness.

Surtronic Duo is a battery powered, portable surface roughness measurement instrument capable of checking multiple parameters in a single trace. surtronic duo measures Ra at the touch of a button and shows the result on a large LCD window.

Cycle time is about 5 seconds and result is saved until another measurement is taken.

Surtronic Duo features:

  • There is no setting up or programming of the device
  • It is ready to use out of the box
