10/14/2019 Manual Densimetro Troxler 3440 Batteries
Recognizing the need for an improved method of measuring the density of thin layer asphalt overlays, Troxler, the world leader in nuclear gauge technology, developed the first true thin layer density gauge, the Troxler Model 4640-B. 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 on-site 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.
Gauges with the Troxler Model 3430 Plus and 3440 Plus. The Model 3430 Plus & 3440 Plus Manual of Operation and Instruction contains information on safely using this gauge. Also included in this manual are safety warnings, gauge setup, troubleshooting, and general maintenance. Before operating the gauge, read this manual carefully.
Advantages of the MODEL 4640-B FAST/ACCURATE RESULTS: In as little as one minute, the 4640-B displays densities in pcf, kg/m 3 or g/cm 3 and in percent Marshall, percent voids, or percent of maximum density (voidless). Accuracies within 1.5 percent of core results have consistently been achieved. ELIMINATES NEED FOR NOMOGRAPHS AND MANUAL CORRECTIONS: Variations in the density or composition of the base material do no affect the test results. No field calculations or charts are needed to determine density. OPERATOR SELECTED DEPTH OF MEASUREMENT: Enter the thickness of the overlay into the gauge memory and then accurately measure the overlay density (compaction) without influence from the underlying material.
ASTM APPROVED: The 4640-B meets or exceeds all applicable ASTM standards. CALIBRATION: Test equipment is only as good as its calibration. With 30 years of proven experience, the 4640-B calibration process is unbeatable for its accuracy and results. For special materials, up to 11 field calibrations can be performed and stored. USER FRIENDLY: The operator will find the 4640-B very easy to use.
It was designed as a user friendly gauge with prompts to guide the operator through the test procedure. DATA STORAGE - COMPUTER COMPATIBLE: Store up to 750 readings by location and project number.
Transfer stored readings to a printer of computer via RS232 interface. Additional site information can also be stored with each test.
