An enhanced version of the standard model, the Zeiss DuraMax HTG coordinate measuring machine is designed to be more insensitive to mechanical vibrations and temperature fluctuations, making it well-suited for use in a production environment. The HTG, which stands for “high temperature and gradients,” is said to deliver accuracy to 3.2 microns at ambient temperatures ranging from 15°C to 40°C. In addition to this increased temperature range, the maximum permissible fluctuations also have been raised, enabling the CMM to operate under temperature changes ranging to 50 percent per hour and 100 percent per day without compromising measurement quality, the company says.

These accuracy improvements are made possible by improvements to machine components, including insulating of the Z axis with a hood. The basic body of the machine also has been equipped with a reflecting stainless steel cover and special insulation.
