Aluminium and steel structure incorporating a high precision inductive transducer. Three units are generally recommended for axial deformation measurement. They can be easily applied to the specimen by a pair of elastic bands supplied as standard. It has to be connected to a suitable data logger or, directly to our Automatic control consoles MCC or ADVANTEST which can provide cyclic loading and automatic determination of the Modulus of Elasticity. A data logger as, for example, our model 82-P9008 http:www.controls-group.comenggeneral-lab-testing-equipmentdata-acquisition-unit-datalog-8.php, can be used with compression testers for axial deformation measurement when it's not mandatory to perform loading unloading cycles, but only loading ramps. In this case, one of the channel of the data logger should be used for the load signal coming from an additional pressure transducer with 3 way connector fitted to the compression tester. Please get in touch with our technicians for complete information and service.

The Bartracker, which use the Pulse induction technique, features a rugged waterproof IP 65 case with a probe storage for easy portability. The battery pack can be recharged inside or outside the gauge. The display screen shows you everything you need to know. The gauge is supplied complete with:Standard search head to meet most of measurement requirements to identify 40 mm dia. bar up to 95 mm depth (approx.), 8 mm dia. bar up to 70 mm depth (approx.), sensing area 120x60 mm, Carry case and instruction manual, Battery pack and charger, Shoulder strap.

This method, which is applicable to cast and cored concrete specimens, concerns the determination of the concrete permeability to oxygen conforming to the Hagen-Poiseuille relationship. The apparatus consists of: Permeability cell for specimens 150 mm dia, 50 mm high, Volumetric gas flow meter, soap bubble type, Digital readout unit and pressure transducer.

The AUTOMAX E-Modulus is specifically designed for the determination of Elastic Modulus and Poisson's Ratio. It is also used for automatic execution of compression, flexure and splitting tests on concrete and cement when connected to a suitable testing frames. The console consists of an ergonomic cabinet which houses the hydraulic system, the electronic boards and the all-in-one PC. PC and software ensure the remote control of the complete system (frame and console) for automatic E-Modulus test execution: rapid platen approach, zeroing, application of user-defined cycles of loadunload ramps, identification of failure load, verification of conformity to the selected Standard, calculation of results, graphical and numerical management of results.

Automatic execution of up to 6 independent triaxial tests from start to finish with only one PC, type of tests: total and effective stress, stress path, K0, permeability and unsaturated soil, -high-speed PC closed loop control for continuous monitoring and istantaneous reaction of systems components,user-friendly software for remote control and test procedure, automation components can be also applied to any existing manual system for automatic mode upgrade,space efficiency design, no need of air compressor (with exception of unsaturated soils tests,ideal solution for high demands laboratories which requires high productivity and reliability.

The automatic ProctorCBR compactor provides a fully automatic uniform compaction of specified effort, thus ensuring repeatable test results and eliminating any operator fatigue during the tests. It consists essentially in a robust steel frame housing the motor speed reducer and lifting mechanism which assure uniformity of drop height at all specimen levels. The rammer pick- up has a cam system for accurate height release and is made of highly resistant material for trouble free long life. Compaction cycles conforming to the mentioned Standards, can be set on the digital control panel. The internal mechanism is protected by a two doors that stop automatically the machine when opened, conforming to the safety CE requirement. The compactor is provided with a 24954535 g hammer with double interchangeable tip 50.8 mm dia. circular face for 4” moulds and sector face for 6” dia. moulds conforming to ASTMAASHTO Standards. It is also possible to convert the compactor to EN, BS and NLT Standards (for 100 mm dia. moulds only), by simply replacing the standard hammer with the 33-T85002 (see accessories) and adjusting the drop height.

The cube and cylinder specimens can be easily locked on the table and the grinding head, 330 mm dia., can be radially moved either manually or automatically in both directions so, the only manual operation requested is the lowering of the grinding head by the top hand wheel. The machine is supplied complete with safety chip guard that, when removed, stop automatically the machine, with coolant tank, motor pump and one set of abrasive sectors. Diamond grinding sectors are available on request (see accessories). The machine is supplied complete with clamping element for 100, 150 and 200 mm cubes. Clamping devices for cylinders and device for dry grinding procedure are also available on request (see accessories). The 45-D0534B and 45-D0534C Core face preparation jigs can be easily fitted by the clamping element supplied with the machine.

The water column type consists essentially of a stainless steel flanged cylindrical vessel with cover assembly, incorporating the measuring cylinder, pressure gauge and valves. Supplied complete with hand pump and calibration cylinder apparatus which is essential for adjustment to site barometric pressure. The cylindrical vessel of all models can also be used as unit weight measure for fresh concrete for density determination.
