A historical device or apparatus used to generate or study static electricity, likely combining 'electre' with a measuring element.
A compound of 'electre' (an older form of electrum/amber) and possibly 'meter' or a variant. This appears to be a specialized 18th-century scientific instrument term.
This obscure word is basically lost to history, representing early scientists' attempts to name equipment before they fully understood what electricity even was—it's a linguistic fossil!
