Tenney T2 Temperature / Humidity Cycling Test Chamber

The Tenney T2 temperature and humidity cycling chamber simulates a wide range of temperature and humidity conditions while utilizing minimal floor space. We specifically designed these environmental chambers to have a compact exterior and an ample interior workspace. 

The T2 Temperature and Humidity Cycling Chamber design allocates space within the interior of the cabinet for all standard options. This greatly improves the mobility of the unit as well as the overall appearance. 

Benefits

  • Easy to use controller
  • Fiberglass and polyurethane around chamber for uniform insulation
  • Minimal thermal transfer for more accurate results
  • Accurate control and display with minimum maintenance
  • No wet wick or water supply required
  • Units are mobile
  • The Tenney T2 Temperature / Humidity Cycling Test Chamber has a minimum footprint

Features

  • Vapor-tight, continuously welded stainless steel interiors
  • Low workspace height to ease the loading and unloading of product
  • Vertical recirculation conditioning system
  • EIA-232 and EIA-485 data communications with Modbus RTU protocol
  • Platinum Resistance Temperature Detector (RTD)
  • Electronic capacitive sensor
  • Chamber overtemperature protection
  • Cascade refrigeration system
  • Built in safety devices
  • Optional: Viewing window (as shown in photo), 6" x 7", thermally insulated and heated (no manual wiper required)

Performance

  • Temperature Range: -68°C to +180°C
  • Humidity capability: 20% to 95% RH in the dry bulb range of +20°C to 85°C as limited by a 3°C dewpoint. Test data based on 24°C ambient, sea level, 60Hz.
  • On 50Hz or higher than 24°C ambient, performance may be reduced. Consult factory regarding any special cooling requirements. CFC-free refrigerants are used exclusively on all Tenney chambers.
