How to use
Install the thermometer on a vertical wall at approximately eye level or another location representative of the room’s ambient temperature. Avoid placing it near direct heat sources, radiators, open windows or direct sunlight to prevent local temperature distortion. Read the temperature on the analog scale where the coloured liquid indicates the current ambient temperature in °C. No power or batteries are required; periodic visual checks are sufficient to monitor room climate.
Usage recommendations
For the most reliable results mount the thermometer on an interior wall away from drafty windows, doors or heat-emitting appliances. If accuracy verification is needed, compare readings with a calibrated digital thermometer at two different stable room temperatures and use the two-point adjustment if small deviations are detected. Clean the wooden housing with a dry or slightly damp cloth and avoid using abrasive cleaners or soaking the device.
