- Density measurement capability in backscatter or direct transmission mode
- Moisture measurement in backscatter mode to allow quick, non-destructive testing of soil, asphalt and concrete materials
- Direct readout of test results (wet density, dry density, moisture, % moisture, % voids, and % compaction)
- Multiple count time options (15 seconds, 1 minute, 4 minutes)
- User-friendly menus and keypads
- Options of 12”/2”, 12”/1” and 8”/2” depth measurement capability
The gauges meet or exceed the ASTM standards D6938, D2950, and C1040.
4640-B Surface Thin Layer Density Gauge
Recognizing the need for an improved method of measuring the density of thin layer asphalt overlays, Troxler developed the first true thin layer density gauge, the 4640-B Surface Thin Layer Density Gauge.
Designed to measure the density of thin asphalt and concrete layers from 2.5 to 10 cm (1 - 4 inches), the Troxler Model 4640-B Thin Layer Density Gauge accurately measures the overlay density without influence from underlying material. No nomographs or manual corrections are required in order to compute the true density of the overlay. With onsite results available in as little as one minute, the Model 4640-B can provide the user with test results when they are needed, not hours after compaction has been completed. |
