Our business is simple. We make ultra precision air temperature control systems to eliminate errors in precision engineering.

The above video demonstrates how one uses a Praecis Environment-5 with a surface analyzer. The pairing provides up to ten times improvement in measurement accuracy.


Have us design a Complete Environment for your equipment or retrofit an Air Temperature Control Unit to your existing enclosure.

  • Improve the accuracy for diamond turning and other precision instruments by eliminating dimensional changes due to thermal variations.
  • A Praecis Environment system can improve the accuracy of a high precision manufacturing process by a factor of two to ten.

We guarantee that a Praecis Environment system will maintain the temperature at the critical point within your enclosure to at least 50 times better than ambient.
