TI-EL18560 School Ammeter 0-10 x 0.01 A DC £27.95 ea TI-EL18562 School Voltmeter 0-20 x 0.01 V DC £27.95 ea
A USB low voltage Joulemeter which includes datalogging and can be used with or without a computer. Simple enough to use at KS3, and flexible enough for more advanced use at KS4 and beyond, the Joulemeter simply requires an input supply and a load to be plugged in (e.g. a solar panel and a motor) and the meter will display the values of the power and the energy transferred. For simplicity, the instrument automatically adjusts the display to show suitable units and an appropriate number of decimal places, so that it can deal with a very wide range of values (e.g. for energy, from 100 nanojoules up to 1.75 megajoules). The meter keeps a log at the chosen sample rate when the total energy transferred is being measured; the data can then be loaded on to a PC using free minidatalogger software.

Multifunction Laser
This multifunctional laser offers the facility to use a single light beam for laser experiments, a horizontal plane light beam for the study of wave propagation and 1 or 3 light beams in a vertical plane for ray optic experiments. The unit also allows studying transmission through a fibre optic using the modulated input for the laser beam. The magnetised base means it can also be used on magnetic boards, for easier demonstration. Can be powered by 2 x 1.5 V batteries (not included) or mains power adapter (included). Specifications: Wavelength: 650nm Power: 1mW (class II) Modulation: TTL signal (5 V) with 4mm safety plug.
LED Light Box & Optical Set
This comprehensive light and optics set includes a 3 beam LED Ray Box - each beam has an option of white or red beam - and a selection of lenses and prisms, comprehensive teacher’s notes and 9 pupil work cards. The set is an ideal accompaniment to any advanced study of light and optics with experiments to show refraction and reflection through various shaped prisms and lenses, the splitting of light into the rainbow colours, how internal reflection is used in fibre optic cables and the appropriate lenses to use to correct long and short sightedness.

Spectral Tube Holder & Power Supply
The spectral tube is mounted from the front in the insulated holders with electrodes, where the lower holder is spring loaded parallel to the tube axis. The holder is provided with a power supply that can deliver 6 kV DC at max 2 mA to the electrodes built into the base of the insulated holder. Can be used with spectral tubes OP66582 to OP94616 (see online) and with many other types of spectral tubes. For 230 V AC. Dimensions: (L x H x W): 78 x 78 x 290 mm.
