✦ Synopsis
Weston's Relative Humidity Indicator Now Has a Fan Attachment.--Accurate humidity readings can now be obtained quickly in factories, shops, rooms and even small, confined spaces near, or in operating machinery, thanks to a new motor-operated fan developed for attaching to any Weston Relative Humidity Indicator.
The small fan, powered by dry cells, will move air over the indicator's wick in sufficient volume to permit obtaining stable readings within 30 seconds. This makes possible complete analysis of humidity conditions in, for example, a textile mill, particularly in and around the machinery while it is operating, thus enabling the adjustment of the humidifiers and air-conditioning equipment for best results.
No calculations are required, as readings are immediately obtained on the instrument's simplified slide rule.
