E-Field Detector
The Lascells 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. 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. The LED array indicates not only positive or negative charge, but also its magnitude. Whole class demonstrations are easily achievable, as the LED display is bright, and illuminates red for positive charge, and blue for negative. The charge magnitude is given by how many LEDs illuminate on the scale. For quantitative measurements, simply attach a voltmeter or datalogger across the 4 mm sockets.
Very quick and easy to setup, the Lascells E-Field Detector is a benefit for specialist and non-specialist teachers alike and is so easy to use that students can gather data themselves. The comprehensive instructions include both traditional experiments that benefit from the use of the Lascells E-field Detector along with new exciting ways to look at charge. This charge sensor makes difficult concepts more understandable and engaging for the students. The Lascells E-Field Detector is a real game changer in the subject of electrostatics.

Greg Lewis –
This is my favourite thing I have bought all year. It’s great for demos – all the physics teachers in my department are very excited about it. We keep finding new uses for it. Fantastic little meter.
