Test Equity 123C

TEST EQUITY 123C

The Test Equity 123C Temperature / Humidty Chamber provides high-end chamber performance in a smaller, upright package. The 123C comes standard with the newer F4T Touch Screen Controller. It's very easy and intuitive to operate. It includes RS-232 and Ethernet interfaces. GPIB is available as an option.

• Non-CFC Cascade Refrigeration

The TestEquity 123C also features:

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

• Heated multi-pane window eliminates fog and condensation without a manual wiper.

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.

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.

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 cur 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 and humidity system for ease of service and preventive maintenance.
