TR-72W Data Logger

Model  Description 
TR-72W   Temperature Humidity Data Logger

TR-72W device utilize an A/C Adapter for power while connected to a network, and utilize a lithium
back up battery which will preserve recordings for up to 3 months.
The TR-72W can even be user calibrated by programming either a one point or two point adjustment factor,
which is internally applied to all displayed and recorded data.
