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.

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 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.

Casters
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.

TECHNICAL FEATURES

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.

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 result is a cabinet that does not sweat due to condensation during low temperature operation.

Heated Viewing Widow
Eliminates fog and condensation without a manual wiper.

Water Recirculation System
The optional W100 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. Perfect for installations where a water line and drain are not available.

Reliability & Safety That's Designed In
Non-CFC refrigerant is used. Expansion valves provide optimum performance throughout the operating range, while keeping the operating pressure within safe limits regardless of load conditions. Liquid injection ensures cool compressor operation during high-temperature pull down for long life. The 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. 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.
