Electrical Impedance Soil Density Gauge

电阻抗土壤密度仪

Contractors who want density and moisture without handling a nuclear source often move to an impedance gauge. Four darts driven 150 mm into the soil measure radio-frequency impedance, giving wet and dry density from 1.2 to 2.6 g/cm³ and moisture to 40 % in about a minute. A soil model is built from five reference tests, and readings are GPS tagged.

Product Description 产品描述

Contractors who want density and moisture without handling a nuclear source often move to an impedance gauge. Four darts driven 150 mm into the soil measure radio-frequency impedance, giving wet and dry density from 1.2 to 2.6 g/cm³ and moisture to 40 % in about a minute. A soil model is built from five reference tests, and readings are GPS tagged.

Highlights

  • Wet and dry density plus moisture
  • Four darts, 150 mm penetration
  • About 1 min per test
  • GPS-tagged readings

Applications

  • Embankment compaction control
  • Subgrade density checks
  • Replacing nuclear gauges on small sites
  • Trench backfill QA
