Additional Product Information

The Features You Want - Included at No Extra Charge...

Programmable Temperature Controller
Up to 256 steps can be programmed into as many as 40 nameable profiles. A large LED readout indicates the actual chamber temperature with 0.1° resolution. 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. Internal logic provides refrigeration compressor control for responsive and reliable performance. Includes event outputs to control remote devices. RS-232C interface is also included. GPIB, Ethernet and analog retransmit outputs 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 upper LED readout indicates the actual chamber temperature while the lower readout indicates the status The limit controller will shut down the chamber and trigger the audible alarm in the event of an out of limit condition. A set of uncommitted contacts are available to provide a safety power interlock for your test sample.

120 Volt Input The chamber draws 18 Amps maximum at 120 Volts. You can plug it into any standard 20 Amp wall receptacle.

Viewing Window and Interior Light
6-Pane window minimizes thermal losses. Oven-rated interior light fixture protrudes minimally into the workspace.

Two 4" Access Ports
Lets you attach wires and sensors to your test sample through both the left and right side of the chamber.

Adjustable Shelf
A heavy-duty stainless steel wire shelf ensures proper airflow around your test sample for uniform temperature distribution.

Casters
Rugged casters permit easy movement.

TECHNICAL FEATURES

No-Sweat Cabinet
We use a combination of structural foam and fiberglass blanket insulation for a higher combined R-factor than just fiberglass alone. The door sealing surface is kept warm by circulating excess heat from the refrigeration system. The result is a cabinet that does not sweat due to condensation during low temperature operation.

Reversible Chamber Door
You won't need to rearrange you whole bench or workflow to accommodate the Model 123C. 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

Reliability & Safety That's Designed In
Non-CFC refrigerants are used in a cascade (two compressors) configuration. Expansion valves provide optimum performance throughout the operating range. Pressure regulators keep the operating pressures within safe limits regardless of load conditions. Liquid injection ensures cool compressor operation during high-temperature pull down for long life. Sequential starting of each compressor reduces the current demand on start-up. Each compressor is protected by high/low pressure switches. 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.

The side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance.
