The gravity convection series oven provides superior uniformity +/- 4.0°C at 100°C. The double wall insulation and 2 inches of industrial fiberglass insulation help to minimize heat loss. Low watt density heater keeps temperatures uniform and therefore keep energy consumption low. Gravity Convection units are preferable for applications with lightweight samples (powders, lightweight films and granular materials) because they do not have an internal fan that may blow these samples around within the chamber.
