Original F4
Temperature 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 two alarms and seven
event outputs to control remote devices. RS-232C communications is also included.
GPIB, Ethernet and analog retransmit are available as options.

High/Low Temperature Limit Controller and Alarm
Provides independent protection against excess temperatures. Both high and
low limits can be set. The limit controller will shut down the chamber and
trigger the audible alarm in the event of an out of limit condition.
Viewing Window and Interior Light
6-Pane window minimizes thermal losses. Oven-rated interior light fixture protrudes
minimally into the workspace.
Two 3in Access Ports
Model 115A chambers include two 3in ports (2.83in inside diameter).
Lets you attach wires and sensors to your test sample through both the left
and right side of the chamber.
Shelf
A stainless steel wire shelf ensures proper airflow around your test sample
for uniform temperature distribution.
Casters
The 115A-F floor-standing version includes casters to permit easy movement, making
the chamber truly portable.
Reversible Chamber Door
You won't need to rearrange you whole bench or workflow to accommodate the
Model 115A. The chamber door is reversible, allowing the door to open from
the left or right side. This is also useful when placing two chambers side-by-side.

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.
Reliability and Safety That's Designed In
Non-CFC refrigerants are used in a cascade (two compressors) configuration.
Pressure controls keep the operating pressures within safe limits regardless
of load conditions. Liquid injection ensures cool compressor operation during
high-temperature cool down for long life. Sequential starting of each compressor
reduces the current demand on start-up. 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. 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.
We use a combination of structural 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 side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance.
