TEST EQUITY 155 Temperature Chamber
TestEquity's Model 155 Benchtop Temperature Chamber combines best-in-class energy efficiency with outstanding temperature control. Using patentpending 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 overdriven to achieve fast temperature settling times during transitions.
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 to achieve unprecedented energy savings and robust temperature control. 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.
