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. A set of uncommitted contacts are available to provide a safety power interlock for your test sample.
Viewing Window
Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.
Two 4in 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.
Chamber 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.
Casters
Rugged 3in casters permit easy movement.
Power Cord with Plug
Heavy-duty power cord has a NEMA L6-30P twist-lock plug. Chamber requires 208V or 230V, 1 PH power.
World's Best Environmental Chamber Warranty
Only TestEquity offers a 3-year warranty on parts and 1-year warranty on labor. Our nationwide service network is qualified to do the job right. 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 & 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 a pressure switch. 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. Each branch circuit is individually protected with class-CC fuses. 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.
