About This Product
This unit offers a quantitative alternative to the gold-leaf electroscope, showing charge as a number in nanocoulombs. A charged body is touched to the 25 mm collecting plate or brought up close to it, and the reading appears on the display. The two 4 mm terminals on top connect to ground and to the charging body, and the reset button discharges the unit whenever required. Export supply of the Digital Coulombmeter 0-1999nC can be arranged to laboratories and schools in Cameroon, Solomon Islands, South Sudan, United Arab Emirates, Latvia and Argentina.
Frequently Asked Questions
Q1. Can the coulombmeter be charged without contact?
Yes. As well as by contact, it can be charged by induction by bringing a charged body up to the 25 mm collecting plate.
Q2. Is a battery included?
No. It runs on an internal PP3 battery, which is not included but is available to purchase separately.
