New and Improved!

The Thermal Anomaly Detector II or TAD II is a significant advancement on the highly successful TAD. It encorperates much faster environment monitoring, with a more sophisticated alarm system which not only detects briefer periods of extreme temperature changes, but allows the user to see what it detected after the event, with the unit staying lit even after the alarm.

Advanced Information

The TAD II conducts a baseline calibration when it starts, flashing purple and cyan until it has completed.

After that point, it measures the temperature many times a second and if this temperature deviates from the average of the past 100 readings by 0.3 degrees, it raises the alarm. The normalise function prevents false alarms, when a hot/cold spot is reported, it doesn’t alert you to the opposite when the temperature returns back to normal.

This function prevents false alarms. In other temp sensors when a cold spot is recorded, they tend to then give a hot spot alarm as the temperature returns to normal.

The TAD doesn't do this. When you see a hot or cold spot alarm, you can be sure that something new has actually happened.
