Product Name: Electrical Soil Density Gauge Edg Sr-4500 Model NO.: SR-4500 Trademark: C-TECH Transport Package: Standard Export Packages Specification: 600x460x370mm Origin: China Mainland HS Code: 90248000 Product Description Electrical Soil Density Gauge Edg Sr-4500The Electrical Density Gauge (EDG) is a nuclear-freealternative for determining the moisture and density ofcompacted soils used in road beds and foundations.The EDG is a portable, battery-powered instrumentcapable of being used anywhere without the concerns andregulations associated with nuclear safety.Its user-friendly, step-by-step menu guides the user througheach step of the testing procedure and cautions the userwhen values do not correspond to established curves forthe material being tested.Easy-to-use, the EDG can be used as a construction aidto monitor day-to-day compaction operations by providingperformance and measurement results highly comparableto those achieved with traditional methods, including thenuclear gauge and/or a sand-cone and oven moisture testcombination.When conducting a test, the EDG measures and displaysthe results for wet and dry density, gravimetric moisturecontent and percent compaction.Model SR-4500Wet density rangetypical compacted earth sites rangeDry density accuracywithin 3% of standard testsMoisture content rangetypical compacted earth sites rangeMoisture content accuracywithin 2% of standard testsOperating temperature0-50ºCAmbient operatinghumidity 5-90%, non-condensingPower Li Ion battery(AA battery optional)Battery lifeapprox. 12 hours of runtimeBattery charger110-240V 50/60HZDimensions600x460x370mmGross weight10kgComponents1. EDG Console/ComputerThe EDG unit contains a computer that applies mathematicalformulas to determine the physical characteristics of thesoil. The computer also contains memory that remainsintact after the EDG has been powered off. This memory isused to save Soil Models and Job Site data. See AppendixA for information on EDG memory capacity. The EDGconsole has an LCD display which is used to provide visualinformation to the user and a keypad that allows the user to key information into the EDG unit.2. Electric Soil Measurement SensorThe Soil Sensor gathers electrical information about thesoil under test and transfers the information to the EDGcomputer.3. Dart Template4. Temperature ProbeWhen performing EDG testing, the temperature probeshould be placed into the soil. The soil temperature is animportant variable in accurate EDG testing.5. Calibration Check Unit6. Soil DartsTo get electrical data from the soil, 4 Soil Darts are poundedinto the ground by a hammer. A template is providedto accurately position the Soil Darts. The Soil Darts aremachined by stainless steel and are expected to last manyyears.7. Battery ChargerThe Battery Charger that is provided with EDG will chargethe battery in approximately 12 hours.8.
