High/Low Limit ControllerHigh/Low Temperature Limit Controller and Alarm
Provides independent protection against excess temperatures. Both high and low limits can be set. The upper LED readout indicates the actual chamber temperature while the lower readout indicates the status The limit controller will shut down the chamber and trigger the audible alarm in the event of an out of limit condition. A set of uncommitted contacts are available to provide a safety power interlock for your test sample.

Viewing Window
Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.

Two 4" Access Ports
Lets you attach wires and sensors to your test sample through both the left and right side of the chamber.

Adjustable Shelf
A heavy-duty stainless steel wire shelf ensures proper airflow around your test sample for uniform temperature distribution.

Rugged 3" casters permit easy movement.

Built-In Refrigeration Gauges
Provides system status for easy preventive maintenance and service.

World's Best Environmental Chamber WarrantyWorld's Best Environmental Chamber Warranty
Only TestEquity offers a 3-year warranty on parts and 1-year warranty on labor. Our nationwide service network is qualified to do the job right. And we always have replacement parts in stock for immediate shipment. Labor warranty applies to the United States and Canada only. See the complete warranty statement here.


TestEquity 1007S Temperature ChamberNo-Sweat Cabinet
We use a combination of structural urethane foam and fiberglass blanket insulation for a higher combined R-factor than just fiberglass alone. The result is a cabinet that does not sweat due to condensation during low temperature operation.

The window is constructed of 6 panes of tempered glass separated by low-conductivity spacers to keep thermal losses to a minimum. Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.

The stainless-steel interior liner is heliarc welded, while the refrigeration compartment behind the liner is double-insulated and carefully sealed. These design features reduce thermal losses and prevent moisture migration, ensuring years of optimum performance while keeping the cabinet rust-free.

Reliability & Safety That’s Designed In
Non-CFC refrigerant is used. Expansion valves provide optimum performance throughout the operating range. Liquid injection ensures cool compressor operation during high-temperature pull down for long life. The compressor is protected by a high/low pressure switch. Care has been taken to use a minimum number of fittings, joints and welds to reduce the possibility of refrigerant leaks.

All electrical control components are UL approved. Each branch circuit is individually fused. A main power disconnect switch is provided on the front panel. The nichrome air-heater has a low watt-density and even heat distribution for reliable performance and fast response. A fusible link provides fail-safe protection against thermal runaways, in addition to the microprocessor-based high/low limit controller.

The side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance. Shown above with the optional circular chart recorder, which mounts conveniently in the front.

Should I buy a TestEquity 1007S Single-Stage or 1007C Cascade Chamber?

TestEquity Single-stage refrigeration systems are capable of achieving workspace temperatures down to -35°C. This is fine for many commercial and industrial tests that require low temperatures of typically 0°C, -10°C or -25°C. A single-stage system uses one compressor to directly cool the workspace. Single-stage systems offer these benefits over similarly-sized cascade systems:

  • Faster cooling rates.
  • Higher live-load capacity.
  • Quieter operation, more energy efficient (one compressor instead of two).
  • Higher anticipated reliability and lower cost of maintenance over the life of the chamber (the 1007S has 35 less parts and 26 less refrigeration connections than the 1007C).

TestEquity Cascade refrigeration systems are capable of achieving workspace temperatures down to -75°C. This is required for many ruggedized industrial, automotive and military tests that require low temperatures of typically -40°C, -55°C or -65°C. A cascade system uses two interdependent compressors. One compressor (low-stage) directly cools the workspace. The other compressor (high-stage) cools a heat-exchanger (cascade condenser) to remove heat from the low-stage. If you need to go below -35°C, choose the TestEquity 1007C.
