The thermal conductivity can be calculated from the temperature difference between the hot and cold end and the heating capacity. The housing contains the vacuum pump and the digital displays. The measured values can be read on digital displays. In this experimental unit, a metal test bar is clamped between a heater and a Peltier element as the cooler. In this way errors due to convection can be ignored and all the heat must flow through the test bar. The complete arrangement is under an evacuated bell jar. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.

The design of Advanced Digital Training System is easy to operate and easy to understand.
The Advanced Digital Training System is designed for the beginners to enhance the comprehension of advance digital theory.
Flow straighteners and guide vanes are used. A choice of between one and three flow pumps can be ordered to provide maximum flow rates between 0.3 and 0.8m/s at maximum operating depths. Higher flow rates can be achieved with a smaller depth of water. 300 x 450 mm flow channel (Advanced flow channels) is designed in a modular way to allow different configurations to be purchased against the current and future needs of the user. The inlet chamber has been designed from experience with cavitation tunnels to provide a relatively stable flow. The basic channel is manufactured in 5m sections such that a length of up to 20m can be purchased. The walls of the channel are made from plexiglass (with toughened glass options), the base of the channel is formed from aluminium (with a stainless steel option), and the frame from a coated mild steel fabrication.

Advanced Refrigeration Training Unit is a multiple circuit unit, incorporating important secondary controls, is constructed entirely from standard commercial components and will give the student invaluable experience in fault diagnosis, system adjustment and replacement of faulty components.
The Advanced Refrigeration Training Unit is a fully operational, small scale cold room, which enables the student to relate all test results, system faults and adjustments directly to situations encountered in service and maintenance.

This board is an option to the board since it uses its oven, the heating element and the temperature transducers. This board includes two reference signal generators, a comparison node and the three terms network (proportional, integral and derivative). The board is supplied complete with a set of stackable, plug-in cables of suitable lengths and colours and with a training manual. Complete with digital temperature indicator 100mV/°C.

The transient response of the sensors can be examined by quickly immersing them in the second tank. Digital instruments for measuring temperature, voltage and resistance enable the characteristic curves to be drawn. A wide range of temperature measurements can be performed and compared using this unit. A 3-channel line recorder can be used to continuously record the measured values from the electrical temperature sensors (thermocouple, thermistor, RTD) and thus to document the different responses. The thermometers and temperature sensors to be investigated are heated to the same temperature in a tank of water. A second heated tank with an electronic control system provides water temperatures up to 80C.

The Aeration Unit comprises an open tank equipped with a paddle stirrer. A variety of diffusers is included. The dissolved oxygen content of the water in the tank is measured by means of an oxygen electrode and dissolved oxygen meter. The equipment consists of a base and backboard standing on four rubber feet. Mounted on the base is the clear acrylic water tank which has a capacity of 24.5 liters. On the front of the tank is a depth scale and at the base a drainage tap. The lid of the tank is partially removable to allow filling. On the fixed part of the lid are mounted the stirrer motor, stirrer and clamping positions for the temperature probe, oxygen probe and aerator tube. Air is supplied by an electrically driven pump through a control valve and flow meter to a diffuser, adjustable for position, within the tank. The meter supplied gives an additional direct reading of water temperature. Air is supplied to the tank by means of a pump with filter and silencer assembly is controlled by a valved flow meter discharging through the aerator tube. Three diffusers, sparger tube, treble airstone and single airstone, may be separately attached to the aerator tube. Operating from internal batteries, the meter may be used for field trials independently of the apparatus. Variable speed adjustment of the stirrer paddle provides different levels of turbulence in the tank. The oxygen/temperature meter is mounted on the backboard with the connecting leads to the appropriate probes.

The equipment consists of a ten litre reactor vessel mounted on a vacuum formed plastic base, with a liquid feed pump, air supply and instrumentation for monitoring and controlling the process.
The porous liner is removable for cleaning, and a spare liner is supplied.
Waste water is drawn from a floor-standing feed tank (not supplied) by a DC motor driven peristaltic pump. Rotational speed and thus flow rate, are accurately set by a ten-turn potentiometer. The pump delivers the feed to the reactor vessel through a transparent lid.
The cylindrical wall of the reactor is made from a porous plastic material to retain the suspended solids while allowing treated water to pass through to the outer, annular exit chamber. This design allows the essential features of the aerobic treatment process to be studied without the distractions of having to settle the solids adequately enough for external recycle - a well known laboratory problem.
Air is supplied at a measured rate by a small compressor, and discharges into the base of the reactor via a spider-arm dispenser, designed to prevent blockages as well as to produce sufficient bubbling for stirring and reaction.
Discharge is by gravity to a floor-standing product tank (not supplied).
The reactor temperature is maintained by a 3-term controller which varies power to an immersion heater within the vessel. Any temperature between ambient and +35deg C may be selected, the best conditions being a few degrees above the diurnal maximum in the user's laboratory.
The liquid level in the reactor is maintained at a constant value of 5-10 litres, by an adjustable overflow device connected to the outer annular chamber of the vessel.

Aerofoil for examination of self-starting vibration
This module consists of a duct with transparent front andrear, between which is mounted a symmetrical aerofoil with a profile. The aerofoil may be accurately rotated to various angles of incidence (attack)to the air using the control and printed scale on the front of the duct. The aerofoil has 12 tapping points at various chord wise positions on its surface allowing the pressure to be measured at that point. The experiment mounts on the Air FlowBench contraction using toggle clamps. Each one of the tappings connects to themanometer (ancillary) via flexible tubes fitted with quick-release couplings. The tapping points are permanently connected to a manifold mounted on the duct showing the tappingposition and number for easy reference.
