The company

Yspekh Sàrl is based in L’Auberson, in the Vaud Jura. The instruments we sell are calibrated and serviced here, in Switzerland — and while yours is in the workshop, a replacement takes over, so that no one is left without a measurement. We answer in French, German, English and Italian.
