Line of Temperature Benchtop and Floor Model Test Chambers These temperature benchtop and floor model test chambers are well-suited for use in electronic, military, and pharmaceutical quality assurance and reliability testing, as well as research testing and production processes. In keeping with the needs of today's lab, we specifically designed these benchtop and floor chambers to have a compact exterior, yet an ample interior workspace to maximize valuable floor space. Features of Tenney Junior
Temperature Benchtop and Floor Model Test Chambers
Construction - All models feature vapor-tight, continuously welded stainless steel interiors.
- Structural reinforcement is used at all critical points.
- A combination of fiberglass and polyurethane insulation surrounds the temperature chamber to maximize insulating characteristics, thus ensuring minimal thermal transfer.
Control Tolerance - ±0.3°C after stabilization
Control System for Tenney Jr. and TU Jr. Temperature Benchtop and Floor Model Test Chambers - The proprietary controller can be used to manually set the chamber at a given temperature, or it may be used to enter, store, and execute a temperature profile.
Temperature Benchtop and Floor Model Test Chambers Control System Features include: - The ability to store 8 programs with
16 segments each. - Programs can be linked together or looped to create a sequence of up to 121 segments.
- RS-485 communications.
- 2 event outputs which can be controlled manually, or may be turned on/off during each segment of a program.
- Guaranteed soak feature.
- Digital displays for both the chamber setpoint, and the actual chamber temperature.
Resolution - Setpoint and chamber temperature are displayed with 0.1°C or 0.1°F resolution.
Sensors - A platinum RTD sensor measures
temperature in the chamber. - The sensors provide excellent control and display accuracy with minimum maintenance.
Refrigeration System - Tenney Hermeticool®: air-cooled, readily accessible hermetic system uses accurately calibrated capillary tubes rather than mechanical expansion valves.
- This simplifies the system and reduces the likelihood of leaks.
Heating System - Low-mass nichrome, open wire heating elements are used to reduce thermal lag and provide rapid response to instrument demand.
- The heating elements are isolated from the workspace to reduce radiant influence on the test item.
Electrical - All wiring in Tenney temperature chambers complies with NEC. Electrical components are located in a readily accessible, integral control panel.
Conditioning System - Uniform conditions are assured through the use of a vertical-down recirculating conditioning stream.
- The system draws air from the bottom of the workspace, conditions as required, then discharges the air through a grille at the ceiling level.
- The compact design of the conditioning plenum allows the test chambers to offer a larger proportional area of interior volume to exterior volume than afforded by conventional chambers.
Door - Since the temperature chamber is continuously welded, the door remains as the final sealing surface to maintain atmosphere integrity.
- All doors are equipped with double gaskets that trap air for the purpose of insulation.
