    hour or more for the meter to reach an accurate reading. Remember that the hygrometer is reading indoor humidity, and is vastly different than outdoor humidity, as reported by the National Weather Service. It is not uncommon to have low humidity reading during cold weather when indoor air is heater. Air conditioning also removes moisture from the air.
  • Page 4: Absolute Vs. Relative Pressure

    weather forecasting. The weather forecast or pressure tendency is based on the rate of change of barometric pressure. In general, when the pressure increases, the weather improves (sunny to partly cloudy) and when the pressure decreases, the weather degrades (cloudy to rain). The weather forecast is an estimation or generalization of weather changes in the next 24 to 48 hours, and varies from location to location.
  • Page 5: Dial Thermometer

    barometer is moved to a new geographic location. 6. Dial Thermometer The dial thermometer uses a bimetallic strip wrapped into a coil. One end of the coil is fixed to the housing of the device and the other drives an indicating needle. The principle behind a bimetallic strip thermometer relies on the fact that different metals expand at different rates as they warm up.
