DF-3540 Deflectometer

Deflection is measured with a single arm with an attached spherical contact tip. The magnetic base furnished with the gauge can be mounted to the desired reference surface, whether flat or round. The tip can then be positioned to measure the deformation encountered during the test. The upper arm exerts a small spring force against the specimen, which is sufficient to allow dynamic cyclic testing if desired, yet light enough in force to avoid influence on the test. These units come standard with the arm set to measure downward deflections when oriented in the upright position. They can be used upside down or in any orientation.

— Travel ranges of 0.15″, 0.25″, 0.5″ and 1″ available
— Comes with an adjustable magnetic base for easy mounting.
— Spring loaded arm disengages to prevent damage from overtravel.
