Benchmaster Temperature and Humidity Test Chambers

Tenney's Benchmaster temperature and humidity test chambers are capable of simulating a wide range of temperature or temperature and humidity conditions. The five cubic foot work space will readily accept equipment as large as a 19"relay rack.

In keeping with the needs of today's lab, Tenney designed these temperature and humidity test chambers to have a compact exterior that maximizes the interior workspace.
