Product Applications

Dickson’s new Flat Panel LCD Recorder lets you view detailed temperature (FT300/325) or temperature and 
humidity  (FH320/325) data on its large screen and allows for optional PC downloads. Its large 4.5” x 3.4” 
display shows you current temperature and humidity readings and displays a graph of data ranging from 1 
hour to 32 days. No paper charts or running back to your PC to see data, this recorder shows you everything 
at the push of a button.

 

 

Ideal for:

 

•  Checking building automation systems

 

•  Tracking Critical Processes

 

•  Monitoring Walk-in Freezers, Coolers and Storage Rooms.
