Aspectu is a new type of thermometer-hygrometer, where the figures are projected through the wooden panel; it also includes an electronic hourglass. The sauna meter can be placed very freely in a suitable place on the wall of the sauna room. A suitable installation height is approx. 30 cm from the ceiling and at least 50 cm from the heater.

The transformer of the sauna meter has 5 m long silicone wires. Aspectu hourglass works in a loop whenever the meter is on. Alternatively, a pushbutton can be connected to the meter, with which the hourglass resets and always starts from the beginning, duration 15 min.

The wooden panel part of the meter is made of Finnish birch plywood and its diameter is 235 mm. There are three basic options of the wooden part: Birch, Hemlock or Kelo plywood. In addition, the client can tone the birch plywood panel with any colour treatment suitable for sauna use.
