The circular disc and axle are mounted with the axle vertical between pivots, one on the base and one on a radial brace from a vertical pillar. The apparatus consists essentially of a low inertia circular disc mounted onto a vertical axle that can be rotated under the action of a falling mass. The upper surface of the circular disc is scribed with circles of 100 mm, 150 mm, 200 mm and 250 mm diameter and two holes are provided on each circle as sites to locate additional inertia discs. The low inertia circular disc, which is 300 mm diameter and 50.8 mm thick, is manufactured from plywood and is keyed to a 12 mm diameter by 305 mm long stainless steel axle. A 50 mm diameter pulley is attached to the axle.

The demonstrates how energy can be saved by regulating compressor rpm and fault simulation switches allow students to diagnose.
A Domestic Air Conditioning Training Unit with Inverter for investigating the hydraulic, mechanical and thermodynamic operation of a split-type air conditioning system equipped with an inverter.
The has been designed and manufactured for safe operation in the laboratory environment and the refrigerant used is a which complies with current legislation.
Students investigate the refrigeration system, mechanical operation and thermodynamic cycles of a split-type air conditioning system with an inverter and understand how changes at different parts of the system affect efficiency.
The apparatus consists of an open channel of rectangular cross section supported at its inlet end by a reservoir tank, and at the outlet end by a frame. A number of test models are provided along with an ink injector to allow streamlines to be observed. This Flow Channel provides a low cost experiment with an easy to set up and use operation. The nominal dimensions of the channel are 20 mm x 150 mm x 650 mm long. The channel walls are made from clear acrylic plastic so that full visibility of the flow characteristics can be achieved.
Experimental Capability:
Study of flow over triangular hump section, demonstration of approximate Specific energy - Depthâ„¢ relationships, comparison of theoretical and experimental values of critical height
Study of flow with variable head inlet and variable head outlet using the adjustable outlet orifice
Visualisation of flow around objects through the injection of ink into the flow
Study of flow under a sluice gate (undershot weir).
This hands-on training program is designed to offer the student a thorough job orientation and skill development for the front-end servicing of vehicles. The Four Wheel Suspension Steering Brake Program system offers complete alignment concept flexibility. from basic front wheel alignment (on the trainer); to a complete four wheel alignment on passenger can.

An electrically-powered device designed to deliver high-flow (exceeding peak inspiratory flow) heated and humidified ambient air or air/oxygen to a neonatal patient as part of noninvasive ventilation (NIV); it may additionally be used with a water tank to produce bubble continuous positive airway pressure (bubble CPAP).
Continuous Positive Airway Pressure (Bubble CPAP) system for the non-invasive respiratory support of normal, premature or low-birth weight neonate with spontaneous breathing. The unit has an integrated pulseoximeter to measure the level of arterial oxygen saturation in blood.
It consists of a gas flow generator that entrains room air, an oxygen input, a heating element, and humidification chamber; it does not include CPAP controlling pressure sensors (i.e., not a full CPAP unit). It is intended for use by a healthcare provider on a spontaneously breathing patient in hospital settings.
To be used with: Scalpel handle no. 4
To cut and dissect tissue during surgical incisions.
Long cuff gloves for gynaecological and obstetric procedures to protect both patient and medical staff from cross-contamination. Gynaecological gloves are sterile and strictly SINGLE USE.
Gloves, gynaecological, latex, powder-free, size: medium, sterile, single use, pair.
Digital weighing scale to weigh adults and children, weighing capacity up to 250kg, with 100g graduation. Powered with customer replaceable batteries. The scale allows a child's weight to be measured while being held by an adult.
Measuring range 0.1 to 250 kg.
Accuracy: ± 100 g over the entire range of measurement.
Graduation: 100 g.
Portability: Easy to carry by a health worker in the field. Maximum weight 4.0 kg (including batteries); maximum dimensions:360 mm for length, 400 mm for width and 70 mm for height.
Mother-child mode is the default mode, alternative mother only mode can be activated by pressing an operational button.
Taring: Taring function is automatically initiated, without pressing any operational button. Taring function is initiated once a parent holds a child after being weighed first (mother child mode).
The on/off button does not serve any other purpose and is encased to be protected from rain, dust and humidity.
Main on/off button has a feature to prevent accidental switching on or off and is easily accessible.
Power saving feature automatically turns off the scale after 4-6 minutes of non-use.
A set of reusable, washable sanitary pads for menstrual protection to be used and reused for a duration of minimum one year.
Each set is comprised of:
2 Holders made of cotton
1 pouch for storage
3 Winged Pads
2 Straight pads
Pad material:
The holders have ribbon bands with edges well stitched by over-locking or other adequate fixation to secure the pads in position.
Pads are made of cotton, preferably flannel, for high absorbance on one side, and synthetic material on the flip side for protection against leakage.
Colors: grey or light brown.
Optimum allow-steel structure and head treatment throughout ensure high strength. the long shank of wrench allows extra leverage without compromising safety.
