Soiltest LC-8 Dial Indicator – 0.001″ Resolution, 1.0″ Range

Soiltest LC-8 Dial Indicator – 0.001″ Resolution, 1.0″ Range

Condition: Used – In original packaging.

The Soiltest LC-8 Dial Indicator is a precision analog displacement gauge used in geotechnical and civil engineering applications to measure small deformations in soil and material test specimens. With a measurement range of 0–1.0 inch and a graduation of 0.001 inch, this indicator is ideal for use in CBR (California Bearing Ratio), consolidation, triaxial, and other ASTM-compliant test systems. Designed by Soiltest Inc., a respected name in soil mechanics instrumentation, the LC-8 offers repeatable accuracy, rugged durability, and compatibility with standard test frame mounts.
