Large Digital Shear Box, by Wykeham Farrance

This new digitally controlled large shear box is ideal for testing geosynthetics and also soils and other materials that contain large particles of up to 120 mm largest dimension.

Sample sizes up to 300 mm square can be tested, with insert allowing the testing of 150 mm square samples.
The shear box has two loading systems, one for consolidation and one for shear.

The sample is consolidated via a hydraulic drive.
This is powered by the Sercomp 7 Automatic Hydraulic Console with PID closed loop control and programmable consolidation load.

The machine includes 100 kN load cell and linear potentiometric transducer 50, 25 and 10 mm travel complete with mounting brackets.
The machine can be connected with the 30-WF6016 Geodatalog data aquisition unit.

Main Features:

•     •  Ideal for testing:
         Shale - Industrial slag - Brick rubble - Colliery spoils
  • •  Digital control
  • •  RS 232 interface allows PC control
  • •  Steplessly variable speed control between 0 - 9.99999 mm/min
  • •  Sample size up to 300 mm
  • •  100 kN shear and consolidation force
  • •  Suitable for testing geosynthetics
  • •  High performance proportional valve and electronic control of vertical pressure
  • •  Graphical and numerical representation of setting parameters during consolidation stage
  •     including the load/time graph
  • •  Up to 100 step of consolidation
  • •  Calibration via software of consolidation hydraulic pump with linear function

New Covermeter from Controls!

The BARTRACKER boasts one of the best measurement accuracy features available today. Rugged, waterproof and ergonomic case with most functions accessible and controlled through 4 simple keys located on the search heads, allowing single handed operation.

The focused search heads enable an accurate measurement in congested situations, giving you the detailed information you need for your site survey.

The class leading resolution of the BARTRACKER Covermeters allows you to achieve accurate readings when there is a minimal distance between rebars. With the choice of extra search heads available as options, which are easily interchangeable and are automatically recognised by the unit, the BARTRACKER can deliver the results you need quickly, easily and accurately.

Using the optional Borehole Probe you can extend the BARTRACKER’s measurement range to locate and orientate additional layers of rebar and tendons up to 100 cm/40” below the surface.

• • Rebar location
• • Rebar orientation
• • Depth of cover
• • Large graphic display with backlight
• • Signal strength bar
• • Interchangeable heads with LED and keypad
• • User selectable bar sizes and numbers
• • Autosize mode for quick bar diameter determination
• • Orthogonal mode bar diameter determination
• • Bar diameter range: 5-50mm in 21 values
• • RS232 output to PC
• • EDTS MS EXCEL link software
• • Data logging
• • Date and time
• • Waterproof (IP65) case
• • Adjustable beep volume and earphone socket

New Troxler 3430 Plus and 3440 Plus Surface Moisture-Density Gauges

Troxler introduces the new and updated versions of the popular gauges which have been offered to customers for many years. The Model 3430 Plus and 3440 Plus gauges have been updated to offer more advanced electronics, updated software, and improved features. These new devices were designed to be very similar to the current nuclear gauges that Troxler customers have become accustomed to, while offering many user-friendly features and some options which are brand new to the industry. Some of these new features and options include a larger display screen, measurement data storage in all gauges, a backlit LCD screen and automatic measurement data storage.

These two models appear very similar to each other, utilizing the same keypad and software, however the 3440 Plus offers many features never before seen on a nuclear gauge. These brand new features include: a remote start keypad, USB data transfer option, loud external beeper, and GPS capabilities (optional).

Both the Model 3430 Plus & 3440 Plus gauges offer these features and capabilities:

• • Direct readout of wet density, dry density, moisture, % moisture, % voids, and % compaction
• • Powered by rechargeable NiMH batteries or backup alkaline batteries
• • Moisture, density, and trench offsets to adjust gauge measurements
• • Larger 4-line x 20-character display screen
• • Measurement data storage in all gauges
• • Backlit LCD screen
• • Automatic measurement record storage
• • Nomograph method for measurement of asphalt overlays
• • Forty years of Troxler experience and an extended eighteen month warranty give you the confidence you need in your field testing equipment

The Model 3440 Plus offers the same basic features as the Model 3430 Plus, but with these enhanced capabilities:

• • Remote start keypad on top of handle
• • USB port for data transfer via removable flash memory (“thumb” drive) or USB printer
• • Loud external beeper to indicate end of a count
• • Automatic indexing - Gauge senses the depth of the source rod automatically
• • Optional GPS (global positioning system) function - Reports latitude and longitude of measurement location at completion of reading
• • Backlit keypad for viewing in dimly lit jobsites

This range of instruments determines moisture content of construction materials. This is a critical factor in determining quality of final construction. The Trident™ utilizes the latest microwave and microprocessor technology to measure moisture content in various fine and coarse-grained sand and aggregates. The prongs of the probe are inserted into the material to be tested and the percentage of moisture content is instantaneously shown on the easy to read display.

The James Aquameter™ is an advanced digital instrument, using a high frequency capacitive sensor to accurately measure the water content of concrete, masonry, brick, gypsum and most solid materials. This line of products represents the most effective and efficient way to evaluate concrete and other materials in the field and utilizes the latest in technology in order to guarantee accurate results.
