MODELS 4200 AND 4200L
GEOKON
Models 4200 and 4200L are designed primarily for long-term strain
measurements inside mass concrete, in structures such as foundations, piles,
bridges, dams, containment vessels, tunnel liners, etc.
The 4200L is a low-modulus version designed to enable early curing strains to
be measured. The length of the 4200 gauge is 152 mm (6”).
