This SmartQ Charge Sensor has now been discontinued.
Please see our latest wireless version for more information.
Wireless Charge Sensor
The Charge sensor can be used in many electrostatic experiments to measure the charge on a source when it’s very small. It can replace a traditional gold leaf electroscope by showing not only the charge polarity (positive or negative) but also the quantity of charge.
In addition the sensor can function as a high-resistance accurate voltmeter to measure the potential difference between two points.
All our sensors are supplied with 5 years warranty and lifetime support.
The Charge Sensor is a very high impedance voltage sensor which will draw practically no current whilst measuring the potential difference between the ends of an electrical component.
Although the Sensor has over voltage protection of ±40 V, this would not be sufficient to protect from the extremely high voltages created by a Van de Graaff or similar high voltage generator i.e. it is not suitable for the direct measurement of Van de Graaff electrostatic generator.
The Charge Sensor can be used to investigate a number of scientific experiments such as:
