Elektronický elektroskop. Na rozdiel od klasického elektroskopu môže však robiť aj kvantitatívne merania. Má extrémne vysoký vstupný odpor, na vstupe je 0,01 µF kondenzátor, čo umožňuje robiť rôzne experimenty z oblasti elektrostatiky. Senzor má 3 rozsahy merania a tlačidlo nulovania (vybíjania) vstupného kondenzátora.
