Tenney C-EVO Temperature / Humidity Test Chamber

Since 1932, Tenney has pioneered the design and manufacturing of environmental test chambers.

Designed for value, reliability and performance, the Tenney C-EVO Temperature / Humidity Test Chamber is a world class environmental cycling test chamber loaded with standard features and advanced technological upgrades:

• Largest temperature and humidity range in the industry
• Smallest equipment footprint in the industry
• Superior Heat Capacity (KW), Cooling Capacity (HP/BTU) and Air Flow Capacity (CFM) deliver the best temperature change rates and uniformity in the industry
• Redundant user and equipment safety features are standard
  Benefits:

• Robust design delivers consistent, reliable, repeatable results that lead to higher productivity
• Improved serviceability and reduced maintenance cost
• Programmable controller - Smart 1.0^TM - is very intuitive - easy to set up and user-friendly
• Constructed for long life and thermal integrity

Smart 1.0 Controller 7 Inch Screen

The main features of the 7” Windows based PLC Smart 1.0 are the high resolution graphical touch screen, Smart 1.0 graphical user interface, 32 bit RISC 400 MHz central processing unit, 4GB (SD Card) flash storage, capable of storing up to 100 profiles with 100 steps each. Test data retrieval and profile data transfer/sharing is accomplished through a local FTP server via Ethernet connection. Individual PID control loops allow for precise process control.

A 100-ohm platinum RTD is used for temperature measurement and a dry capacitance type sensor is used for humidity measurement (when applicable). Customer use event outputs events can be purchased as an option.

Other features included with Smart 1.0:

• Real-time and historical color graph displays for temperature and humidity as well as set point values
• System can run in Single set point or Programmed modes
• Alarm, Program, and Datalog files can be easily transferred to and from controller via Ethernet connection
• Built-in TCP/IP networking via Ethernet 10/100 communication port
• Ethernet communications are standard. RS485, RS232 and IEE GPIB are all available as options
• Optional Analog signal re-transmit out to peripheral devices such as optional chart recorders, etc.
• Remote access via Smartphone, iPad, etc. with internet connection and VNC phone App’s
