DE-MOUNTABLE MECHANICAL STRAIN GAUGE AZA1170
The AZA1170 De-Mountable Mechanical Strain Gauge is a precision instrument designed for accurate strain measurement on concrete, rock, steel, and composite specimens. Built in full compliance with ASTM D5335, this mechanical gauge offers high-resolution deformation monitoring for both laboratory and field applications where reliability, repeatability, and portability are critical.
Unlike bonded electrical strain gauges, the AZA 1170 is reusable and non-intrusive, requiring no adhesive, wiring, or power supply. It attaches to pre-installed gauge studs and measures deformation mechanically via a micrometer-style dial gauge with an accuracy of ±0.002 mm. This makes it ideal for temporary measurements, comparative strain evaluations, and multi-point deformation studies across multiple specimens.
Engineers and researchers use this instrument widely in uniaxial/triaxial compression testing, tensile tests, rock mechanics, material durability studies, and structural health assessments in dams, tunnels, bridges, and underground structures. Its rugged yet lightweight design enables quick installation, stable readings, and efficient workflow during intensive testing cycles.
The AZA 1170 features an adjustable gauge length from 50 mm to 200 mm, with optional extension arms and interchangeable dial indicators to suit various testing protocols. All components are machined from corrosion-resistant aluminum alloy or stainless steel, ensuring dimensional stability even under harsh environmental conditions.
The system includes a calibration bar, mounting tools, and a protective carry case, enabling users to maintain accuracy and safely transport the device between field and laboratory sites.
