The cord is coupled to force measuring devices with a strain gauge via a tension spring. The unit is used in conjunction with the basic module for the experiments, cylindrical weights are placed on a horizontally rotating stainless steel disc. Using this experimental module, static friction and sliding friction, and the related friction vibrations and slip-stick effects can be clearly demonstrated. This is prevented from turning by a cord. An open container surrounds the friction disc. Different lubricants can be placed in this beaker.

K-type thermocouples measure the inlet and outlet water and air temperatures, as well as permitting the connection of the air velocity sensor.
The air mass flow rate is derived using an air velocity sensor.
Some parts in the heat exchanger such as probes and axial fan can be easily removed for cleaning.
Enables variation of the parameters involved in the cross flow exchange process and therefore a complete analysis of the phenomena.
A comprehensive instruction manual is included.
Mounted on a PVC base plate which is designed to be installed on the plinth of the Heat Exchanger Unit without the need for tools.
The Hydraulic Troubleshooting Learning System is the first product to offer a realistic electrical component troubleshooting experience for students because the faults are inserted throughout the system, including the hydraulic, mechanical and electrical components. The Hydraulic Troubleshooting Learning System teaches hydraulic troubleshooting like no other product by providing a hands-on learning station that models a real world hydraulically-powered machine and includes over 40 faults that can be inserted into the system. The Hydraulic Troubleshooting Learning System is set up like a real machine with realistic loads, pressures, and heavy-duty hydraulic components, just like students will see on the job! This feature also makes the Hydraulic Troubleshooting Learning System an excellent system for teaching advanced hydraulics, system tuning, installation, and maintenance. Hydraulic application panels include: power unit controls, rotary load, compression load, and overrunning load. The mobile hydraulic troubleshooting workstation consists of a sturdy welded-steel frame with interchangeable drive panels and motors, enabling students to quickly set up different drive applications. Safety is emphasized throughout the curriculum using lockout/tagout, emergency stop pushbutton, safety disconnect switch, and actuator guards. The Hydraulic Troubleshooting Learning System consists of a mobile workstation, with hydraulic power unit, (4) machine application panels, PLC control, fault insertion system, hydraulic troubleshooting and servicing package, student learning materials for both theory and lab, and teachers guide.

The set contains 18 aluminium drawing models. The cylindrical models have cut-outs parallel to, and at an angle to, the main axis. The models are precision-manufactured and are suitable for measurement exercises as well as drawing exercises. The geometric models support the learning process by providing an introduction to technical drawings: from the solid model to the more abstract representation of the three views in a technical drawing. Two students can easily work with one model set. For optimal learning, it is recommended that students work independently from each other on these exercises.

The Compression Ratio can be changed without stopping the engine and without altering the combustion chamber geometry by means of a specially designed tilting cylinder block arrangement. Setup is provided with necessary instruments for combustion pressure and crank-angle measurements. Computerized Variable Compression Ratio Engine Test Bed allows to perform experiments concerning this kind of engines. The unit consists of single cylinder, four stroke, Variable Compression Ratio (VCR) engine connected to eddy current type dynamometer for loading. Provision is also made to interface airflow, fuel flow, temperatures and load measurement. Rota meters are provided for cooling water and calorimeter water flow measurement. The test bed includes a stand-alone panel box consisting of air box, two fuel tanks for duel fuel test, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator.
