Electric Muffle Furnace is designed for laboratory and industrial applications. It is used for engineering tests of soils and aggregates, cement testing, ashing organic and inorganic samples, gravimetric analysis, ignition tests, etc. Cases are welded steel construction; perforated base case design keeps bench top cool. Heating elements are embedded in refractory cement for structural strength and long life. The furnace is insulated with Insulight molded ceramic fiber insulation; a percentage input controller allows desired temperature to be selected with repeatable results. It also features a fluorescent digital display. Each unit contains a Chromel/Alumel thermo-couple directly connected to 32-2200°F, 0-1200°C dual scale pyrometer. These precision-engineered products are favored for their following characteristics: Uninterrupted operation Robust construction Low maintenance Capability to operate in extreme conditions.
