This dead weight pressure gauge calibrator made of a precision machined piston & cylinder assembly mounted on levelling screws.
The gauge is thus subject to known pressures, which may be compared with the gauge readings and an error curve drawn.
A Bourdon gauge is supplied for calibration. The weights supplied are added to the upper end of the piston rod, which is rotated to minimise friction effects.
A simple deadweight tester with weights and a bourdon tube pressure gauge with a clear front allowing the mechanism to be viewed. The unit has an optional pressure transducer available allowing the concept of electronic representation of pressure to be investigated. Unique design allows standard Newton weights to be used; hence reinforcing the student understanding of pressure being Force / Unit Area.

The Deep Bed Filter Column is a clear acrylic unit with flanged end pieces to allow easy access. Plain tubes also penetrate the medium through the wall to transmit pressure to a manometer system. The medium is supported on a corrosion resistant gauze mesh below which is packed 1kg of 10mm Ballotini to ensure good wash water distribution. Slotted sampling tubes inserted through the wall penetrate into the media, and are fitted with control valves so that suspension samples can be taken isokinetically.
The column can be operated as a pressure filter up to 1 barg. The service system supplied comprises a pump, sump tanks, flow controller, Rota meter, control valves, tubing, sampling tubes and bank of water differential manometers .
These sampling and manometer probes are located at 20mm depth intervals, but staggered in position, over 0.8m depth. Consequently, complete profiles of concentration changes in the suspension and of pressure variation can be measured during filter operation.
Fully automated external defibrillators (AEDs) deliver a high-voltage electrical impulse to the heart in order to restore normal rhythm and contractile function in patients who are experiencing ventricular fibrillation (VF) or ventricular tachycardia (VT) that is not accompanied by a palpable pulse. AEDs are designed for use primarily by first responders to cardiac emergencies, who may not be fully trained in advanced cardiac life support (ACLS). In the prehospital setting, these emergency personnel can include EMTs, firefighters, and law enforcement officers. Flight attendants, security guards, and others −sometimes called targeted responders may be expected to use PAD units. AEDs differ from conventional manual defibrillators in that AEDs can analyse the ECG rhythm to determine whether defibrillation is necessary; this eliminates the need for the user to interpret the cardiac rhythm before delivering a shock. AEDs can also be used in areas of the hospital where advanced life support personnel are not readily available.

An ECG monitor included with the unit is used to verify the presence of a shockable rhythm and the effectiveness of treatment. Defibrillators deliver a high-voltage electrical impulse to the heart in order to restore normal rhythm and contractile function in patients who are experiencing ventricular fibrillation (VF), ventricular tachycardia (VT), or another shockable rhythm.

Test beams fit onto the backboard using a rigid clamp and knife-edge supports. Students apply loads at any position using hangers holding various masses. The experiment hardware consists of a backboard that fixes to the Multi Structures Test Frame.
The indicator measures beam deflection. Scales on the backboard show the position of the indicator, the loads and supports. Mounted on a trammel, a digital deflection indicator traverses the beam.
Features:
High-quality structures teaching module for students of mechanical, civil and structural engineering
For study of beam deflection under different loads and fixing conditions
Realistic and verifiable experiment results
Optional AII's Structures Software package for extra virtual experiments that simulate and confirm the results from your hardware and allow extended experiments
Allows safe and practical experiments into deflections of beams and cantilevers
Ideal for classroom demonstrations, or students working in pairs or small groups
Optional unit including AII's Structures Software package for automatic data acquisition and virtual experiments
One of many interchangeable experiment modules from AII's modern, flexible and cost-effective Structures teaching system.
