The Proctor Needle Spring Type is a compact, easy-to-use device designed to determine the moisture content and compaction characteristics of fine-grained soils directly in the field. Widely used in geotechnical engineering, road construction, embankment work, and soil investigation projects, this instrument helps verify whether soil has achieved the required compaction as per standard Proctor values.

Featuring a precision-calibrated spring mechanism and a clearly marked gauge, the Proctor Needle provides quick and accurate penetration resistance readings. Its interchangeable needles allow testing of soils with different densities, making it a versatile tool for field technicians and construction quality control teams. Lightweight, durable, and reliable, this device is essential for ensuring proper soil compaction and long-term structural stability.
