Ghosthunting paranormal equipment Hot/Cold Spot Temperature Anomaly Detector

The Thermal Anomaly Detector II is a paranormal investigation device used to detect sudden cold or hot spots.

It encorperates fast environment monitoring, with a  sophisticated alarm system which not only detects brief periods of extreme temperature changes, but allows the user to determine how dramatic the anomaly was.

The TAD II self calibrates upon startup so that it increases or decreases it's sensitivity to change depending on how fluctuating the temperature is in the current location.

It measures the temperature many times a second and if the temperature deviates from the average of the past 100 readings by 0.3 degrees, it raises an alarm. 
Red indicates a hot spot, blue indicates a cold spot.

The TAD II is specifically designed to detect these sudden changes, commonly linked to paranormal activity, and not slow changes in temperature which naturally occur.

These devices are custom built in the UK and based on 20 years of investigation using data  logging technology, so the pattern of change it is looking for uses the information gained in all this research.
