Used TENNEY JR #51092 for sale

TENNEY JR is an environmental chamber, designed for testing materials in various climates and thermal conditions. The chamber features a forced convection equipment designed to provide uniform temperature and humidity levels, while a large storage capacity enables users to maintain large material samples. JR also offers optional air capture and exhaust fans that can be employed to create a negative pressure environment within the chamber, while a built-in heat load can be used to simulate heat or cooling tests. The chamber itself is constructed of 316 stainless steel, with a hinged door and is rated for a temperature range of -40 degrees Celsius to +180 degrees Celsius. At the center of the chamber is a built-in fan, which is driven by a variable-speed motor, ensuring consistent and even temperatures throughout the chamber. For added security, an external digital keypad control locks the chamber when idle and requires a key to unlock it before any test run. A Programmable Logic Controller (PLC) is built into the chamber, allowing for user-programmable start and stop points. Programming options include setting temperature, time, conditioning rate, and operating mode. Additionally, the controller user interface can be accessed through an RS232 port, allowing for remote, internet-based programming from anywhere in the world. TENNEY JR is also equipped with an internal data logger, capturing and storing pertinent test data, including temperatures, relative humidity, times, alarms, and door openings and closings. In addition to the internal data logger, the environmental chamber can be connected to a variety of external data loggers, allowing for near real-time analysis of test results. As a safety measure, JR boasts an alarms system with adjustable time delays, allowing for automatic shutoff in the event of a unit failure. An integrated web interface is also offered, allowing for remote control of the machine and near real-time monitoring of test conditions. TENNEY JR offers a high-quality, thermo-mechanically stable environment, enabling the user to simulate virtually any climate condition and material stress, while providing them with powerful data logging capabilities and remote monitoring capabilities. This powerful environmental chamber is designed to provide reliable and consistent results, no matter the application.
