As an economical alternative, ESI Prüftechnik GmbH offers second-hand completely overhauled hardness and spring testing machines as first choice – at a price which is well below that of a new machine. We make the used machines fit again for their second highly productive lifetime in our own workshop. The "new old ones" not only receive a new outfit, but are also mechanically upgraded as new or are mechanically overhauled.
Because these Retrofit Machines are as good as comparable new version, ESI Prüftechnik GmbH gives a 12-month manufacturer’s guarantee. The purchaser of these machines has the very same advantages as if buying a new machine.
