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. 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.

• LED array indicates not only positive or negative charge, but also its size
• External voltmeter sockets allow for quantitative measurements
• Very quick and easy to set up
• So easy to use that students could gather data themselves
• 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
• 24V AC-DC adapter included.
