About This Product
The detector shows whether a positive or negative charge has been created and in which direction the electrons have moved. Its LED array gives the sign and size of the charge, while the external voltmeter sockets provide an output for quantitative measurements. The included instructions cover traditional experiments as well as new ways to look at charge. Export supply of the E-field Detector can be arranged to laboratories and schools in Zambia, Chad, Libya, Bolivia and Zimbabwe.
Frequently Asked Questions
Q1. How do the Hi and Lo sensitivity settings differ?
Hi sensitivity displays 6-125 pC with a minimum resolution of 6 pC. Lo sensitivity displays 0.6-12.5 nC with a minimum resolution of 0.6 nC.
Q2. Can the detector give quantitative readings?
Yes. The external voltmeter sockets give 0-4.7 V, equivalent to 0-470 pC on Hi sensitivity or 0-47 nC on Lo sensitivity.
