THE IDOLEZALEK-PATTERN ELECTROMETER

Combines great sensitiveness, small capacity and high insulation with convenience in handling. The sensitiveness can be changed in a few moments by changing the quartz fibre suspension. The voltage required for the needle is only from 50 to 200.

We are now adding to these instruments a convenient charging key, which enables the needle to be momentarily connected to a source of voltage and then insulated (in this case the fibre is not to be rendered conductive). The needle will thus maintain its charge without appreciable loss for some days, so

that accurate quantitative work can be done, even when the only available voltage is that of the electric light leads, or a statically charged rod, &c.
