What makes the 500 different... Hot and Cold spot alarm.
The new ATDD feature detects subtle Ambient temperature changes in the environment, and converts the Hot and / or Cold change into an audible and visual alarm. Each degree change produces a unique tone.

There is a one Octave step for each degree change which allows the user to quickly differentiate any temperature change even without looking at the display. Blue LED's are used for a temperature decrease, while Red Led's are used to show any temperature increase that occurs.
