• The V Funnel apparatus is used to evaluate the flow time of freshly mixed selfcompacting concrete.
• The test is not suitable when the maximum size of the aggregate exceeds 22.4 mm.
• The discharge is equipped with a lid, which can be momentarily opened.
• The test set consists of a stainless steel funnel placed vertically on a supporting stand.

• The instrument consists of a circular base with Two vertical guides.
• The Hammer of weight 13.75 +/-0.25kg can be raised to fall freely down the vertical guides.
• The Height of fall can be adjusted through 380 +/- 5mm.
• The Hammer is provided with a locking arrangement.
• The hammer falls freely to the base and is removable for employing.
• Supplied complete with metal measure 75mm dia x 50mm high.
• Tamping Rod 230mm long x 10mm diameter.
• It is robustly designed to determine the aggregate impact value of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact.
• A Blow Counter to count the number of strokes is fitted on top of the equipment.

• The Tile sample is pressed under a specified load against a grinding path strewn evenly with an abrasive powder revolving at the rate of 301 revolutions per minute.
• The wear of the tile is measured using a thickness gauge.
• The rotating disc and grinding path are enclosed by a circular tray.
• A bracket holds the specimen. The loading is a counter balanced lever.
• A funnel is provided to facilitate charging the grinding path with abrasive powder.
• Consists of a replaceable grinding path fitting on to a disc rotating its vertical axis.
• Supplied complete with an automatic pre-set revolution counter and one 7.5kg weight but without abrasive powder and thickness gauge.
• Suitable for operation on 230 Volts, Single phase, AC supply.

• A portable digital stroboscope for general laboratory use, such as speed measurement and motion studies. 
• It emits a white light flash from a high efficiency LED solid-state light source on the front of the unit. 
• The rear panel holds the stroboscope controls and a liquid crystal display.
• Stroboscope has two modes of operation: internal oscillator and external trigger.
• Internal oscillator produces a continuous flash over two frequency ranges. 
• External trigger allows another frequency generating device to control the flash rate.
• In addition, the stroboscope can be used as a strobe tachometer to measure speed instead of using a laser tachometer. Using a stroboscope you can “stop” the shaft down to 30 RPM (FPM).

The LED array indicates not only positive or negative charge, but also its size. The external voltmeter sockets allow for quantitative measurements. Very quick and easy to setup, the Science Lab Export E-Field Detector is a benefit for specialist and non-specialist teachers alike and is so easy to use that students could gather data themselves.

The Psaw India E-Field Detector provides a new and novel way to demonstrate charge. This highly sensitive electronic device is an essential piece of equipment in the Physics teachers’ armoury as it can detect very small charges and their polarity, as well as charge at a distance.
The comprehensive instructions include both traditional experiments that benefit from the use of the Science Lab Export E-field Detector along with new exciting ways to look at charge. This makes difficult concepts more understandable and engaging for the students.
Until now, in the school science lab, it has only been possible to demonstrate opposite and like charges by repulsion and attraction experiments or the very delicate Gold Leaf Electroscope. This unique, robust piece of equipment allows the Physics teacher to clearly show whether a positive or negative charge has been created and in which directions the electrons have moved.
This is a real game changer in the subject of electrostatics.
24V AC-DC Adapter included.

• We also have Digital Ammeter & Digital Voltmeter and Digital Galvanometer available.

• For use with Free Vibrations Experiments, the Test Frame fits on any standard desk or bench top. 
• Students, teachers or lecturers fit the parts of their free vibrations experiments to the Test Frame to study or demonstrate a free vibrations topic. 
• The Test Frame has two extruded alloy horizontal members each with slotted fixing points to all four sides. 
• The two triangular sides each have adjustable levelling feet. 
• A stable, level Test Frame is essential in vibration experiments to give repeatable and accurate results. 
• Include a storage tray and lid with the Test Frame.
• The sturdy construction is necessary for accurate results in vibration experiments, but this also gives the frame a long service life. 
• The Test Frame also includes a hexagon tool and a spirit level for easy assembly and levelling.
• Despite its sturdy construction, the frame is light enough for two people to move it around the classroom easily.
• This is useful to store tools and smaller parts of your optional experiments, helping prevent accidental loss or damage.
