This is a Visual Ambient Temperature Sensor with 2 ambient
Probes that are constantly comparing the difference in temperature.
Picks up changes in the ambient air temperature and displays
the change using a Blue light for Cold, and a Red light for Hot.
Tailored for Paranormal Investigation's to detect Hot/Cold
spots that we can't see with our eyes.
Ambient White light to detect the unit in the dark.
Automatically resets every 30 seconds if the ambient air has
a constant change it will auto-adjust to that change while still displaying the
hot and cold changes. All you have to do is turn the unit on and it takes it
from there. Great visual piece to find hot/cold spots during an investigation.
Show's up great on Camera so you can document the temperature Visually!
Works off 4 x AA Batteries.
