Only TestEquity offers a 3-year
warranty on parts and 1-year
warranty on labor at your
domestic site. Our nationwide
service network is qualified to
do the job right. And we always
have replacement parts in stock for immediate
shipment.
Compact Size
The TestEquity Half Cube™ temperature chamber
is small enough to fit on your bench with plenty of
room to spare. It’s 40% smaller and uses 33% less
power than the typical “benchtop” chamber. Put it
on a cart, and you can roll it into even the smallest
work cubicle.
Programmable Temperature Controller
Easy to use microprocessor-based controller stores
256 steps in up to 40 profiles. Includes an RS-232C
interface. Optional GPIB interface is available.
High/Low Limit Control
Provides user-adjustable independent protection
against excess temperatures.
Low-Noise Operation
The Half Cube’s refrigeration system generates a low
level of audible noise and vibration. You’ll be able to
work close to the chamber with minimum discomfort
and distraction.

Programmable Controller
Up to 256 steps can be programmed into as
many as 40 nameable profiles. The context
sensitive information key and guided steps
make profile programming fast and easy. A
four-line backlit LCD displays programming,
setup, operating and help information. A
large LED readout indicates the actual
chamber temperature with 0.1° resolution.
Internal logic provides refrigeration
compressor control for responsive and
reliable performance. Includes an RS-232
interface. Optional GPIB interface is
available.
High/Low Limit Controller
Provides independent protection against
excess temperatures. Both high and low
limits can be set. The limit controller will
shut down the chamber in the event of an out
of limit condition.

Rate of Change: To calculate rate of change for a particular condition, take the difference
between the Start Temp and End Temp and divide by the Transition Time.
Cool Down Example (empty): From +85°C to -20°C = 105°C / 17 min = 6.18°C/min.
Heat Up Example: From -40°C to +85°C = 125°C / 11 min = 11.36°C/min.
* Note: Transition times are measured after a 30 minute soak at the respective start temperature.

Power Requirements
Note: Performance is typical and based on operation at 23°C (73°F) ambient and nominal
input voltage. Designed for use in a normal conditioned laboratory. Operation at higher
ambient temperatures will result in decreased cooling performance. Low end limit
derates to -38°C when operating above 27°C (80°F) ambient. Operation above 30°C
(85°F) or below 16°C (60°F) ambient is not recommended.
Refrigeration and Heating System
Compressor 1/3 HP Copeland hermetic
Condenser Air Cooled
Heater Power 500 Watts
Input Voltage 120 V nominal (110 to 126 VAC), 60 Hz, 1 PH
Current Draw Max Current Draw 10 A, Recommended Service 15 A.
Instrumentation
Temperature Controller 256 steps, 40 profiles, ramp and soak programmable
memory. RS-232C interface.
Limit Controller Independent high and low temperature limits, user
adjustable.
Plugs Into Any 120V Outlet
The Half Cube draws only 10 Amps
maximum at 120 Volts. You can plug it
into any standard wall receptacle, with
plenty of power to spare for other
equipment.
Reversible Chamber Door
You won’t need to rearrange your whole
bench or workflow to accommodate the
Half Cube. The chamber door is
reversible, allowing the door to open
from the left or right side. This is also
useful when placing two Half Cube
chambers side-by-side.
