ATCU-18 All

• We guarantee that a Præcis air temperature control system will maintain the
   temperature control in an enclosure to 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.
