Gold Leaf Electroscope (Sheet Metal)
The metal case tends to eliminate vagrant deflections some times caused by charges residing on glass walls. The leaf support rod is the case are of glass to give good visibility.
Gold Leaf Electroscope (Glass Flask)
This practical and economical electroscope consists of leaf mounted on metal rod hold by rubber stopper in a conical flask. The shape of flask is such that it gives ample space for the leaf to diverge when charged.
The instrument has cup wheel consisting of three conical cups in a horizontal plane. The cup wheel spindle is of stainless steel and connected worm gearing to a revolution counter mounted in water proof housing. By observing the counter reading at the beginning and end of any period of interest the average wind speed during the interval can be calculated. The counter observing window is sloped to permit easy reading when mounted on the mast.
The unit is encased in a special aluminium case with standard stem of 9mm dia. It is fitted with high class optics. Light from two different sources falls on either side of a uniform opaque white screen. This light is reflected by side reflectors (Special prisms) and passes through the Lummer Brodhum cube. The field of view can be seen through a telescope and the light intensities are compared directly. The photometer is mounted in a swivel bracket for proper adjustment with two-nose lamp house & electric bulb is in a metal cased with cord & pin finished optical block.
