TEST EQUITY 107 -  RENT

The Test Equity 107 Temperature Chamber is small enough to fit on your bench with lots  of room to spare. It is smaller and uses 33% less power than the other similiar benchtop chambers. In addition, the TestEquity 107 Chamber  fits in a 19" rack. Low audible noise makes the Model 107 ideal for use in confined workspaces. Requiring only 10 Amps at 120 V, you can plug it into any outlet. There is no need for a dedicated power line. The chamber door is reversible, to open from the left or right side. Two 3 " ports let you attach wires to the test sample through the left and right sides. Cools down to -42 °C without LN2 or CO2.

The Test Equity 107 Temperature Chamber features a number of improvements over the older 105A TE Chamber, including:

Improved Airflow - The conditioning plenum is improved to accommodate a larger fan blade and a more ideal airflow pattern. This results in substantially improved temperature uniformity under real-world loading conditions.


Cools Down to -42 °C - Improved airflow and a larger evaporator (cooling coil) allows the Model 107 to get 2 °C colder. This allows you to compensate for offsets that can occur with an energized load at -40 °C.


Full Bi-Directional Heat/Cool Control - Provides more responsive temperature control, particularly at moderate temperatures.


Choice of Manual or Programmed On/Off Mode - Allows the chamber to be turned off completely at the end of a stored profile or via computer interface.
Deeper Interior - The inside is 3.25" deeper to accommodate larger test samples.


Condensate Drain - The chamber floor has a drain to permit removal of condensate from the evaporator that can occur when cycling between low to high temperatures.

Specifications of the Test Equity 107 include:

  • 0.7 Cu Ft Workspace, 12W x 9H x 11.25D (20 liters)
