Tenney VacTenney Vacuum Test Chambers perform product testing and MIL-SPEC testing, and they can be incorporated into many commercial production processes. The chambers provide a complete vacuum system and control system that is pretested and ready to operate. You only need to connect the chamber to an electrical power source.The basic vacuum chambers are designed to function at vacuum levels up to 20 mm Hg (80, 000' altitude). Vacuum pump systems of greater capacities are available with vacuum capabilities up to 0.169 mm Hg (20, 000').uum

Tenney vacuum ovens are designed for drying, curing, outgassing, aging, process control and many other applications which require elevated temperature in reduced atmospheres. The vacuum oven includes microprocessor digital control, built-in over temperature protection as well as a door with full viewing window.
