TestEquity's Model 155 Benchtop Temperature Chamber combines best-in-class energy efficiency with outstanding temperature control.
Using patented control architecture, it consumes 74% less energy than previous models to maintain 0°C. The chamber features a control tolerance of less than ±0.08°C, operates over a range of -20°C to +130°C with 0.01°C display resolution, and provides 0.55 cubic feet of workspace. With the ability to control the DUT temperature directly, air temperature is precisely over-driven to achieve fast temperature settling times during transitions.

  • 0.55 Cu Ft Workspace, 12W x 8H x 10D (15.73 liters)
  • -20°C to +130°C Temperature Range with 0.01°C resolution
  • F4T Touch Screen Controller with Integrated Limit Controller
  • Air Temperature or Part Temperature Control
  • Platinum RTD Temperature Sensors for the Highest Possible Accuracy
  • 3" x 1.75" Cable Slots on Left and Right Side
  • Compact Size for Benchtop Use
  • Reversible Door
  • Non-CFC Single-Stage Refrigeration - No LN2 or CO2 Required
  • High Efficiency Tri-Mode Cooling for up to 74% Power Savings (Patent Number 10,126,032)
  • 115/230V Switchable Input - Plugs Into Any Outlet
  • 3 Year Parts, 1 Year Labor Warranty
  • Made in the USA
Model 155 offers superior temperature control with unprecedented energy efficiency.

TestEquity's new Model 155 Benchtop Temperature Chamber combines best-in-class energy efficiency with outstanding temperature control. Using patent-pending control architecture, it consumes 74% less energy than previous models to maintain 0°C. The chamber features a control tolerance better than ±0.08°C, operates over a range of -20°C to +130°C with 0.01°C display resolution, and provides 0.55 cubic feet of workspace. With the ability to control the DUT temperature directly, air temperature is precisely over-driven to achieve fast temperature settling times during transitions.

Tri-Mode Cooling Control

In every other chamber on the market, the compressor always runs at full speed when cooling, regardless of how light the demand for cooling is. This wastes a considerable amount of energy and dissipates extra heat into the room. TestEquity's Model 155 uses a miniature DC Variable Speed Compressor and patented control architecture (Patent Number 10,126,032) to achieve unprecedented energy savings and robust temperature control.

Mode 1 - Cools as fast as possible. Compressor runs at 100% speed, refrigerant flow is at 100%.

Mode 2 - Compressor speed begins to vary when approaching the temperature set point or maintaining set points when the demand for cooling is high. The refrigerant flow is simultaneously pulse width modulated as required.

Mode 3 - When demand for cooling is minimal, such as holding a temperature set point after stabilization, the compressor runs at minimum speed. The refrigerant flow is pulse width modulated to maintain the temperature set point. This mode saves 40% on energy consumption compared to the same compressor running at full speed. When compared to our popular Model 107, the total energy savings is 74%.

Part Temperature Control

In all temperature chambers, the temperature of your DUT will always lag the air temperature due to its mass and the proximity from the air source. This causes the DUT to take a significant amount of time for its temperature to stabilize after the ar temperature has reached its set point. Additionally, the DUT may never reach the desired set point temperature, especially if it is energized. Part Temperature Control eliminates these issues. Part Temperature Control (also known as cascade control) is a multi-loop control system where the air temperature set point (Inner Loop) is determined by deviation of the part temperature (Outer Loop) from its set point. The controller is configured at the factory to allow the Air Temperature to deviate up to +10°C or –10°C from the Part Temperature set point. This allows the air temperature to be precisely "overdriven" to achieve the fastest temperature settling times during transitions.

DUT never quite reaches the temperature setting. Longer test time if you actually wait for the DUT to reach Set Point.

Air temperature is biased higher/lower in a precise manner for the fastest response at the DUT.

F4T Touch Screen Temperature Controller

The F4T is our next-generation controller. Featuring a touch-screen interface, it's exceptionally easy and intuitive to use. Includes RS-232 and Ethernet interfaces. GPIB is available as an option.

Plugs in to any outlet worldwide.

Since the Model 155 uses a DC compressor, we are able to power the cooling and heating systems using an internal DC power supply. This allows the Model 155 to operate from 90 to 132VAC or 180 to 264VAC, 50 Hz or 60 Hz, with a rear panel switch for voltage range selection.

Cable slot on the left and right side.

A cable slot provides easy entry and removal of wires and sensors that are attached between your test sample and equipment outside the chamber without having to remove the wires. A silicone plug is provided to seal the cable slot.

Compare the Model 155 to our popular Model 107 and see the many advantages.
