Description

TEMP-POD
Unique Way to Monitor Temperature Changes
This listing is for 2 units. One is the old style with the cream colored top, the other is the newer style with the blue colored top.
Who wants to be alerted when a temperature change occurs? Temp-Pod automatically sets to the existing ambient nearby temperature baseline. When a temperature change occurs, Temp-Pod will emit a distinct tone for each degree change. A momentary Red (Hot) & Blue (Cold) LED will indicate trend of temperature change. If the temperature increases by 1 degree and remains steady for more than 10 seconds, the sound will automatically Mute until the temperature changes up or down by more than 0.1 degree. Great for working in low light conditions. Arrange several in a grid pattern to monitor a large areas.  Requires one 9v per unit, these are included.
