Consists of 5 plywoood beams with grooves. Supplied with 4 fulcrums & 40 \nmetal blanks 25mm square., fi ve plywood beams 600 x 44 x 3 mm graduated \nevery 38 mm and with groove across its centre to locate the fulcrum \npoint. Also included ar
A 250W tungsten filament bulb available with bayonet fitting, internally silvered.
A cluster of three LDR’s, connected in parallel, to provide increased \nsensitivity and better control of current directly in a reed relay.
Easy assembly - no soldering ! The line tracking robot will follow a black line with its tracking sensor. You can design your own route for the robot using a black marker pen, black electrical tape etc. No soldering is required. Asse
4mm pin, 18mm long spring insert for making firm contact with the socket into which inserted and solder nipple for attaching wire lead, fixed to a screw on hard plastic body. Overall length of plug about 40mm.
With transparent glass body. Quick blow type. 20 mm long and dia. 5 mm.
Rheostat of excellent quality. They are wound with heavily oxidized resistance wire upon a vitreous \nenameled steel tube. The winding is locked into place with ceramic cement. The tube is carried upon \nrobust enameled die-cast end stands. 4mm so
An excellent model to study the generation of electric current. Produces either AC or DC current when the hand wheel is turned. The generation of AC/DC Voltage is represented by two bulbs fitted on the base. A sw
Pillar mounted on plastic base supporting two pith balls in un-spun silk.
For showing slow AC on an oscilloscope or meter or for demonstrating the use of a dynamo in lighting a lamp. This apparatus has a cycle dynamo mounted on a base. Two 4 mm. socket terminals are provided for the dynamo output. For a visual output a
Semi-circular convex mirror, 115mm x 50mm high. Depth is 75mm Made in stainless steel and polished on outside surface.
Two photo gates which can be used as a light operated timing gates. Fitted with a pair of 4mm terminals to allow \nconnection to electronic timers. When the light gates are switched on it creates a short circuit, \nwhich becomes an open circuit ea
A mains operated Ultra Violet light source ideally suited to demonstrate use. Comes complete with an on/off switch. The tube is 45cm long and is housed in a UV reflective plastic housing. Suitable for showing the fluorescing propert
Made from soda glass, these tubes are easy to seal in a Bunsen flame and break into two. Supplied in robust tube holder, pack of 100 tubes. Tube overall length is 100mm Tube diameter = 1.9mm, inner diameter = 1.3mm and wall th
Metal strips of size about 200x12mm (length x width), of different metals, each supplied in pack of 10
To show the force exerted by atmospheric pressure. A light walled tin plate can 260x75mm (height x diameter), with an airtight neck and screw cap. A small quantity of water in the can is boiled vigorously until steam occupies the space inside the
ZPH-202 pH Bench meter - A proffesional quality bench meter Large 18mm LCD Display Calibration certificate Power: 1x 9V Alkaline battery not inc
The ADM-930 digital multimeter is suitable for use by electricians, electronic engineers, general industry & laboratories. It is EN61010-1 CAT III 600V, CATII 1000V rated. A large high contrast LCD, a single positive action ro
Non-RoHS Photoconductive cadmium sulphide cell with a spectral response similar to the human eye. As light falling on the cell increases, so the resistance of the cell decreases. Peak spectral response: Typ. 550 nm
A range of encapsulated solar cell modules mounted in sturdy black polycarbonate cases. The faceplate consists of tiny bubble magnifiers which maximise performance by enhancing light as it strikes the cell. Monocrystalline constructi
The SEP Wind Turbine is ready-assembled and can be used to carry out a wide range of experiments on wind power. The blades of the turbine can be easily attached, removed or adjusted, allowing students to investigate the effects of changing the num
Building on the success of the SEP Energymeter, this new USB version boasts datalogging and an improved specification: Current range: ±7A (current can flow in either direction) Voltage range: ±25V
This liquid is non-toxic liquid paraffin containing a UV sensitive photochromic dye. Indoors it appears as a clear liquid but when exposed to natural light it immediately becomes coloured. This colour increases in intensity when exposed to direct
These pigments normally have a pale, off-white appearance but in sunlight or UV light they instantly change to a bright, vivid colour. The pigments revert to their pale colour when away from sunlight or UV light. If the pigment is mixed with a bin
