The Charge sensor BT19i measures electrostatic charges. It can replace a traditional electroscope by showing not only the polarity of the charge but also performing quantitative measurements. The sensor has three operating ranges, which can be selected using a switch.

Range: -5 ... 5 nC, - 25 ... 25 nC , - 100 ... 100 C
Resolution (12-bits): 0.0025 nC , 0.013 nC, 0.05 nC

Can be used to:
• measure magnitude and sign of the charge on diff erent objects,
• investigate electrostatic phenomena,
• charging by induction, friction and by contact.
