PM-521 MEASURE – RAIN GAUGE

A round bottom flask is used as a sphere. Sunrays are focussed by the glass globe of the sunshine recorder, which charr a piece of paper dial. From the length of the charred portion the hours of sunshine can be calculated. Apparatus consist of round base with levelling screws and central rod with a plated tommy bar and arc shaped plate which can be adjusted by tommy bar to set the flask globe at required latitude. Supplied with 12 spare printed dials.
