The Charge Separation Rods are designed for use with the Lascells E-Field Detector.
The Earth Grounding Plate is designed for use with The Lascells E-Field Detector but can also be used in any situation where an earthed working surface is required to neutralise electrostatic charge.
When insulating materials rub together, electrons transfer from one to the other and, since the charge cannot be conducted away, the charge is retained on the surface.
The Lascells battery eliminator is a light-weight and compact power supply intended to reduce the science departments’ need for batteries.
A Digital voltmeter for use in school electronics work, the unit gives accurate readings and saves batteries with its auto-off feature.
