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 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.
Accurate Humidity Measurement
A fast responding Vaisala capacitive-type sensor eliminates the need for unreliable wet-wicks.
GN2 Purge Capability Standard
For low humdity conditions below 6°C Dewpoint (requires customer-supplied gaseous nitrogen supply). More Info >>
Event Relays Standard
Four uncommitted solid-state relays are provided to switch the power to remote AC devices via the F4 Temperature/Humidity Controller.
120 Volt Input
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.
A heavy-duty stainless steel wire shelf ensures proper airflow around your test sample for uniform temperature distribution.
Rugged casters permit easy movement.
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.
Accurate Humidity Measurement
A fast responding capacitive-type sensor eliminates the need for unreliable wet-wicks.
Reliable Vapor Generator
Unlike "atomizing" systems, the heated vapor generator has no pump to fail or orifice to clog. The stainless-steel vapor generator assembly is double-protected against low-water and over-temperature conditions.
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.
Water Recirculation System
The optional water recirculation system provides a reliable source of demineralized water for the humidity system, using ordinary tap or pre-filtered water. Condensate from the chamber is returned back to the water tank. The recirculation pump operates only when needed to fill the chamber's humidifier to the correct level. Perfect for installations where a water line and drain are not available.

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 and humidity system for ease of service and preventive maintenance.
