Lab Ovens: Gravity Convection Digital

Quality gravity-convection ovens feature double-wall construction and heavy, welded-steel exterior. Work space is insulated from the outer cabinet with one inch of high-density mineral wool, and interiors are made of corrosive-resistant aluminized steel. Low-watt density incoloy-sheathed elements are used. Include automatic thermocontrol, pilot light heat indicator and a top-mounted, mercury thermometer (0°-300°C). All ovens come with two, adjustable shelves and a 6 ft., 3-wire power cord and grounded plug. Units also have scratch-proof rubber feet, full-length piano-hinged door and extruded thermoplastic door handle.

The digital control combines the features of the analog model, but offers the ease of temperature setting and the stability of a full PID microprocessor that accurately maintains settings within +/- 0.5°C (1°F) at any given time. The digital controller features large LEDs that continuously display set temperature and process temperature, as well as a setting lock mode that provides protection against accidental or inadvertent adjustment.

Energy-efficient, low-watt density, incoloy sheathed elements are engineered into a compact design for quick run-up and recovery times. Temperature uniformity is greatly improved by a perforated heat shield which absorbs radiant heat and distributes it more evenly throughout the product chamber.
