New automatic control offers simple, reliable operation at the touch of a button. Temperature is set by turning knob and depressing "push to set temperature" button. Digital display conveys chamber temperature (unless "push to set temperature" button is depressed) Temperature range 100-1100°C. Ceramic fiber insulation permits faster heat-up, reduces energy consumption Embedded heating on top and both sides improves chamber gradient. Drop-down door doubles as a convenient shelf for loading and unloading. Door safety switch removes power from the heating elements upon opening the door. If sensor opens, sensor break protection removes power to heating elements, eliminating run away conditions. Applications: ashing organic/inorganic samples, heat treating small steel parts, ignition tests, gravimetric analysis, determination of volatile and suspended solids
