Tenney T2 Test Chamber

Tenney’s new T2 Chamber is capable of simulating a wide range of temperature and humidity conditions while utilizing minimal floor space. These chambers are well suited for use in electronics, military, and pharmaceutical quality assurance and reliability testing, as well as research testing and production processes. In keeping with the needs if today’s lab, we specifically designed these chambers to have a compact exterior, yet an ample interior workspace to maximize valuable floor space.

  • All models feature vapor-tight, continously welded stainless steel interiors
  • New design allocates space within the interior of the cabinet for all standard options, which greatly improves the mobility of the unit as well as the overall appearance
  • New touch screen controller provides precise control over chamber operations and monitoring, and is mounted at eye level (VT III and 94Z are not touch screen)
  • Workspace height has been lowered to provide efficient loading and unloading of product
  • The sensors provide excellent control and display accuracy with minimum maintenance
  • New design provides maximum performance with minimum footprint
  • Uniform conditions are assured through the use of a vertical-down recirculating conditioning system
  • Vapor tight interior made of 100% stainless steel
  • Non-settling, asbestos-free insulation
  • Proprietary VersaTenn control system
  • Watlow 942 Controller (temp only models VT III temp/humidity models)
  • Control tolerance of ±0.3ºC
  • Hermetic refrigeration system
  • Tenney VaporFlo humidity system
  • Low mass nichrome, open wire heating system
  • NEC wiring compliance
  • Vertical-down recirculating conditioning system
  • Double silicon gaskets on doors
  • 2″ diameter access port with plug
  • ±2% RH typical after stabilization
  • IEEE/488 interface
  • LinkTenn software for Windows that permits your computer to control up to 10 chambers
  • RS422, 423, 232, or 485 interface assemblies
  • Upgrade to VersaTenn (standard on T2RC)
  • Water reservoir for humidity system (5 gallon)
  • Recirculating system for humidity water
