Tenney Classic Temperature / Humidity Cycling Test Chamber

Benefits

  • Provides a wide range of temperature and humidity conditioning with many features for optimal tests
  • Uses environmentally friendly, CFC-free refrigerants and durable refrigeration systems
  • Hi-Lo pressure and oil pressure switches stop compressors from exceeding preset limit conditions, assuring safety of product and operator
  • Controllers feature advanced LCD display, allowing for fast and easy programming and configuration of the Tenney Classic Temperature / Humidity Test Chamber

Features

  • Semi hermetic refrigeration system
  • Vertical recirculation conditioning system
  • Automatic defrost for door gaskets
  • Non-corroding parts on all humidity capable units
  • Low water protection
  • Open-air low mass nichrome wire heater elements supported by ceramic insulators
  • Single stage or cascade refrigeration system
  • Vapor-Flo I humidity generator (for capable units) with bell jar configuration

Performance

  • Control accuracy: ±0.3°C and  ±2% RH
  • Standard humidity conditions: 20% to 98% RH in the dry bulb range from + 20° to + 85°C, as limited by a 3° dewpoint.
  • Chamber models with a 'S' suffix indicate a single stage refrigeration system with one compressor.
  • Temperature control range: -40°C to +200°C,  ±0.3°C
  • Chamber models with the 'C' suffix indicate a cascade refrigeration system and two compressors.
  • Temperature control range: -73°C to +200°C, ±0.3°C
