PM/PMF Series
Mold Gage

This gage has been specially designed for measuring interior strain in concrete and mortar under a loading test. The PM is sealed between thin resin plates, and the PMF employs super engineering plastics capable of superior water-proofing characteristics.

Main Test Materials Concrete
Mortar		 Materials Backing Acrylic(PM)
Special plastics(PMF)
Operating Temperature -20 to +60°C Materials Element Cu-Ni alloy wire(PM)
Cu-Ni alloy foil (PMF)
Compensation range - Strain limit 2%
(20000×10-6)
Bonding adhesive - Fatigue life at room temp. -
