Autographic Unconfined Compression Apparatus Manufacturer,Supplier and Exporter in India
Product Code : TVT-STE-10586
The Autographic Unconfined Compression Apparatus is a portable, self-recording instrument used to determine the unconfined compressive strength of cohesive soil specimens without needing a separate chart recorder or data logger.
How It Works
As the operator turns the handle to compress a calibrated spring against the soil specimen, the recording chart is raised automatically, producing a continuous load-deformation trace (an "autograph") of the test in real time. This built-in recording action removes the need for manual reading and logging at each load increment, making the instrument convenient for portable, field-based unconfined compression testing.

Applications
This apparatus is used to determine the unconfined compressive strength of cohesive soil specimens per ASTM D2166: Standard Test Method for Unconfined Compressive Strength of Cohesive Soil and IS 2720 (Part 10): Determination of Unconfined Compressive Strength, with the added convenience of an automatic load-deformation record suited to field laboratories and site investigation teams without bench-mounted recording equipment.

Frequently Asked Questions
What does "autographic" mean for this instrument?
It means the load-deformation chart is recorded automatically as the test proceeds, rather than requiring the operator to read and log values manually at each increment.
Is this apparatus suitable for field use?
Yes, its portable, self-contained design makes it well suited to site or field laboratories where a bench-mounted motorized frame is not practical.
Which standard governs this test?
ASTM D2166 internationally and IS 2720 (Part 10) in India govern the unconfined compressive strength test.
