All models provide PID microprocessor temperature control at operating temperatures from 50 to 1125 °C (90 to 2057 °F). Furnace chambers are molded from alumina silicate ceramic fibers. Use of this material provides low thermal mass for fast heat-up and cool-down, as well as an unusually low exterior furnace temperature for safe operation. The furnace is heated by electric resistance elements embedded in easily removable side and base panels. The heating elements are designed to ensure extended service life, even in atmospheres characteristic of high-sulfur coal and coke samples. Temperature readouts and control parameters are shown on two red 7-segment displays. Two LED's indicate when heater power is being applied or when an over-temperature error condition is encountered. Temperatures can be displayed in either °C or °F. For operation with chamber atmospheres other than air (N2, C02, etc), external gas supplies connect easily through a provided 3/8-inch port. An Injection Port Kit (10-550P) connected to the exhaust port allows convenient venting of the chamber. Isotemp furnaces incorporate a variety of safety features. When the furnace door is opened, power is automatically cut to the chamber heating elements. The heater power is also cut out when the chamber temperature exceeds the set temperature by 25°C (45°F) or more. The alarm condition is indicated on the display while the alarm LED is lit. A ventilated base design prevents damage to the bench or countertop. The system microprocessor permits the user to customize a heating program of up to 24 ramp and soak steps. The model 750 can store four 24 step programs, while the model 650 can store one 24 step program. If desired, a soak period of up to 23 hours, 59 minutes and 59 seconds may be interspersed between any two successive ramps. *Please see pictures for details* Also, feel free to ask any questions pertaining to this item.
