A replacement for the traditional gold leaf electroscope.
Allows the quantity of charge and polarity to be recorded and not just the presence of charge.
1-minute on Charge sensor: measuring a static charge
Additionally the sensor can function as a very high resistance (at least 10 to the power of 12 Ohms), accurate voltmeter. Six ranges, 3 for different charge intensities and 3 for voltage. Ideal for measuring charges developed by rubbing acetate, polythene or ebonite rods.

Charge: ±10 nC, ±100 nC, ±220 nCVoltage: ±0.5 V, ±2 V, ±10 V
Not suitable for the direct measurement of Van de Graaff electrostatic generator.
Determine the sign of charges Using a charge sensor we can go further than the electroscope and show both the magnitude of the charge and the sign of the charge. A big step up form electroscope work.
Activity to show that charges can be added to a collecting surface.
Leaking charges We are always told that charges leak away due to the permettivity of air and point discharge loci. But how how much does leak away?
Faradays Ice Pail Investigate the charges on a Faraday's ice pail. Using the Charge sensor you can see magnitude and sign of the charges collected and induced.
Charge from movement Watch charges being built up as you move around! fun activity and also good for explaining how the wrong trousers can create an explosion!
