FACT: The TH-2A thermometer detects ambient 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. In the paranormal field, the ambient air temperature thermometer is better because cold/hot spots appear out in the open; where the ambient thermometer will detect it better than a surface thermometer.
HOW TO USE: The first thing you want to do is to get a base reading so you can compare your data later on. Press the yellow button to take temperature readings. You have to set the thermometer to either Fahrenheit or Celsius, by pushing the button. While in the field you want to scan the area looking for any temperature changes. If you get a cold spot or a hot spot then investigate the area. When the investigation is complete make sure to write down your readings in the field report.
RANGE: The Temperature range on this meter is –4 to 140 degrees Fahrenheit. The relative humidity range is from 1% to 99%. The range from the meter to the active field is 0 – 1 foot.
READINGS: A normal reading is usually a 5-degree difference from your base reading. Typically a paranormal reading has a minimum of a 10-degree 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. This meter also detects the relative humidity in the air. This is good to know when you’re taking photographs because if there is high humidity, you may capture vapor orbs as a result.
