Tenney ENVIRONMENTAL Junior Compact Temperature Test Chambers
Junior Compact Temperature Test Chambers
The Tenney Junior temperature test chambers have been in the market for over 50 years. They are well suited for use in electronic, military, and pharmaceutical quality assurance and reliability testing, as well as research testing and production processes. In keeping with the needs of today’s lab, we specifically designed these benchtop and floor chambers to have a compact exterior yet an ample interior workspace to maximize valuable floor space.
Features
