The Track-It™ RH/Temp Data Logger is a battery
The on board data storage is non-volatile so data will not be lost in the event of a depleted battery. The Track-It™RH/Temp Logger can be ordered with or without an LCD display. Information displayed on the LCD is also user programmable and can be sequenced by pressing the logger button. Both models have a multicolored LED indicator to notify user of alarms or general activity. A splash proof protective cover protects the logger when in use.
