Air Temperature Control Unit-2

The ATCU-2 accommodates enclosure size range:

Enclosure Area:  0.5 to 3 m²
Volume:  1 to 6 m³. 


Ultra-Precision Temperature Control For Atomic Force Microscope And Tabletop Precision Operations.


• We guarantee that a Præcis air temperature control system will maintain the temperature control in an enclosure ± 0.003 °C.

• Præcis systems provide long-term temperature stability and do not require operator intervention. The ATCU screen displays the temperature in real time, and if the temperature should go out of range, the ATCU will sound an alarm.

• If your Præcis Environment system should need adjustment, Præcis provides remote tuning from its headquarters.
