FACT: The Temp Data Logger detects ambient air temperatures in Fahrenheit or Celsius.
THEORY: In theory when a spirit/ghost starts to manifest, it will draw in heat energy around the area, causing either a cold spot or a hot spot. A cold spot would form because the heat energy is being sucked out of the air causing the air around the entity to be cold. A hot spot would form because the heat energy is being sucked out of the air and confined to a specific area causing a hot spot.
SAVING THE DATA:
RANGE: This thermometer will take readings within a 1-foot radius around the thermometer.
READINGS: A normal reading is usually a 5-degree difference from your base reading. A paranormal reading is usually a minimum of 10 degrees increase/decrease from your base reading. If you get a drop in temperature, the drop is called a cold spot. You may also get an increase in temperature, which would then be called a hot spot. Hot spots are rare but they do occur.
