Another new evolution, in the field of indicators available for Tinius Olsen and other manufacturers concrete compression testing machines, is ECO 2. Version II of our successful ECO will display a force live reading during the test but report peak stress along with peak force when test is complete. The working features of ECO II are:

-  User enters test specimen area before starting a test, it’s stored.

-  During the test the instantaneous force is displayed.

- When test is complete the display automatically alternates between peak force and peak stress results.

TO ECO 2 head is supplied with TO 4 pillar compression machines and available for retro fits.
