The Electrical Density Gauge (EDG) is a non-nuclear alternative for determining the moisture and density of compacted soils used in road beds and foundations. The EDG is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety. Its user-friendly, step-by-step menu guides the user through each step of the testing procedure. The EDG is easy to use and can be used as a construction aid to monitor day-to-day compaction operations by providing performance and measurement results highly comparable to those achieved with traditional methods. When conducting a test, the EDG measures and displays the results for wet and dry density, gravimetric moisture content and percent compaction.
The EDG measures the electrical dielectric properties and moisture levels of compacted soil using high, radio frequency traveling between darts driven into the soil being tested. The dart's depth of penetration positively determines the depth of measurement. Darts are available in 4, 6, 8, 10 and 12" lengths. In addition, the darts have been designed with a taper, which ensures a continual positive contact with the soil for accurate measurements.
The Percometer is a reliable, accurate, lightweight and easy-to-use instrument for measuring the dielectric value , electrical conductivity and temperature of materials indoors and outdoors. Dielectric value is an indication of the volumetric moisture content and the state of molecular bonding in a material. Electrical conductivity is a reflection of ionic concentration, water content and temperature.
The Percometer utilizes two basic probe types, permitting the use of multiple probes with the same central unit. Each probe is identified by the central unit by its unique probe number, and uses a probe-specific calibration table in the central unit’s memory.
The Percometer is an invaluable and effective instrument for use in the following areas of materials: moisture damage (structural damage), suction properties (aggregate moisture susceptibility), asphalt air voids (pavement quality), soil moisture, frozen or unfrozen soils, frost susceptibility, salinity and sulfates, fertility, snow (ski wax control), and temperature.
The Swiss-made Profoscope was designed to meet the pressing needs of the construction and building industry looking for an accurate rebar detecting instrument that is also affordably priced. The new Profoscope offers the best-in-class mix of attractive features to price ever seen by the market. The ergonomically designed instrument fits comfortably in the palm of the hand for easy operation and provides both visual and acoustic indications of what lies directly beneath the concrete surface. Additionally, it has the ability to detect midpoints between rebars for drilling applications.
The new Profoscope is a valuable tool for these applications and would be typically used by general contractors, civil contractors, drilling specialists, electrical contractors, civil engineers, educational institutes, building inspectors and plumbing contractors.
Other benefits of the Profoscope: a fully-integrated and compact design, user-friendly operation, a language-independent menu, wide measurement ranges, regional settings and much more. The Profoscope is supplied with a start-up test kit, a custom-made canvas bag as well as the necessary product documentation and accessories.
The Phunque Flask is the key element in a newly developed method for conducting specific gravity/absorption determinations for aggregate. This method has been designed to eliminate the inherent guess work built into ASTM C128 and AASHTO T-84— the current cone and tamper methods in use today. The test is easy to perform, easy to understand and easily reproduceable between technicians and labs; and is very easy to run reliably in the field. The test can be especially helpful in asphalt operations where specific gravities can make a big impact on pay factors. This test lets the contractor check specific gravities on the material he is currently using, and not rely on lab tests, which may not be current.
The test provides repeatable and consistent test results despite the use of different labs or technicians. It also enables the contractor and DOTs to begin to come to terms with the inherent problem of how much the aggregate from a given pit or source varies, both by location within the pit, and from different fundamental geological characteristics.

Non-destructive strength testing of concrete has a whole new look thanks to the new SilverSchmidt Test Hammer. The new SilverSchmidt redefines strength testing with the use of what is called a "Q" value as opposed to the classic use of an "R" value. What this means for you is that the new SilverSchmidt provides a more accurate method of measuring impact and rebound, which eliminates the need for referencing a chart, based on orientation, to determine the strength of concrete. The new SilverSchmidt calculates the test results for you and provides the concrete strength in any of the many user-defined measurement modes.
The SilverSchmidt (impact energy 2,207 Nm) provides an easy-to-use graphical, icon interface that provides the operator complete control of the test parameters and results display. Review of test data can be performed for the last 20 measurements.
The H-2971U Silverschmidt Hammer adds Hammerlink software to the basic B model, which allows the user to download data from the hammer to a PC where he can analyze data, print reports and archive information. Both models include USB kit (USB cable, USB-stick and USB charger global), carrying strap, grinding stone, chalk, user manual, quick reference guide, certificate, impact templates and carrying case.

The ConMatic IPC is a fully-automated, incremental pressure controller for performing incremental consolidation and one-dimensional swell tests. The ConMatic IPC allows consolidation and constant load and volume swell tests to be run automatically, freeing up technicians for other tasks and reducing the duration of the testing procedures by more than half—effectively saving time and manpower and increasing lab profitability. One ConMatic automated system can replace the production of several manual machines— running incremental consolidation tests according to ASTM D2435 Method B, where successive load increments are applied after 100% primary consolidation.
Once a sample has been placed onto the test platform and the test conditions set, the ConMatic IPC, used in conjunction with a computer and Humboldt’s HMTS software, performs all consolidation tests, including moving to the next stress level, without operator assistance. The system automatically moves through the different test parameters specified by the user with incremental consolidation tests typically being completed in 24 to 48 hours.
The unique design of the ConMatic IPC system enables the user to choose from multiple tests and run them independently and simultaneously.
