The Tenney BTRC Benchmaster Environmental Temperature & Humidity Chamber is capable of simulating a wide range of temperature and humidity conditions. The Tenny Benchmaster chamber provides a workspace of five cubic feet, readily accommodating equipment as large as a 48.26cm relay rack. The Chamber features a vapor-tight interior liner made of 100% stainless steel that is continuously welded under inert gas. Reinforcement is use at all critical points, and through ports are continuously welded. It uses a two-stage refrigeration system to control cooling, a set of electrical heater elements to provide heating, and Tenney VaporFlo humidity generator systems. It simulates a temperature range from -73 to +200 °C and relative humidity range from 20 to 98%. It has a control tolerance of ± 0.3 °C and ± 2%. The Tenney Benchmaster Chamber uses a Synergy Quattro controller to allow full automatic and proportional-integral-derivative (PID) chamber control through a user-friendly alpha-numeric display.
