Heating elements in all three walls, bottom, and door create a warm air jacket around the inner chamber to guarantee superior temperature uniformity with no hot spots. Warm air jacket design also provides quick temperature recovery—and there’s a full-length inner glass door for viewing specimens without disturbing the chamber atmosphere. No need to worry about heater element damage from spills either—the inner chamber is tack-welded, and the low-watt density heating elements are safely isolated from the work chamber.

Microprocessor controlled for easy keypad set and calibration. Temperature display may be calibrated to match a secondary thermometer. For over-temperature protection, a second, independent safety controller can be preset and has visual alarm when activated. All units are stackable without the need for spacer racks. Features through-wall access port for chart recorder. A UL-approved, vapor-tight electrical outlet is inside the sealed chamber. Adjustable leveling feet compensate for uneven surfaces.
