| Price 4/6 ROTOTHERM THE NEW THERMOMETER The accurate thermometer with the speedometer dial and speedy response. With this instrument the temperature can be read accurately and as easily as the time. The Outside model Rototherm can be used either for wall fixing inside or outside and is supplied with fixing screws for bracket and wood screws for securing to frame on the outside of the window. FIXING. The instrument should be removed from its backplate which can be screwed into position on the fixing bracket and then attached, preferably to the fixed section of the window frame. This can be done in a few minutes, after which the Rototherm, which is a friction fit into its backplate, can be pushed into position. The casing is finished in special water-proof finish and the system proofed against corrosion. It is essential that the outside temperature is known so that provision can be made in the way of special clothing, and every bedroom window should be fitted with the Rototherm. Seasonal illnesses and colds can be practically avoided by dressing according to the outside temperature. The Rototherm is indispensable in the greenhouse and cold frame, and is a boon to garage owners during the cold weather. A few seconds paid daily to the study of temperature will obviate loss and damage during frosty weather. A large variety of other models are available for household, desk and industrial uses, particulars of which will be sent upon application.
