Track-it TM Pressure Temperature Logger

The Pressure Temperature Logger is a sealed (IP67) Data Logger used for measuring air

or liquid pressure and ambient temperature. The unit is self contained in a small 316L

stainless steel enclosure with a threaded ¼” NPT port to connect to a pressure source.

The Logger can operate unattended for months or years. Recording parameters can be

set in the Track-It TM PC Software. The unit can be set to record on instantly, at present

times, or on alarm conditions. Up to 64,000 readings can be saved in non-volatile

memory at intervals from 2 seconds to 24 hours. Internally there is a USB port for direct
