Fisher 650-58 laboratory furnace
Digital display and microprocessor controlled
Up to 24 steps in program mode
Internal heat chamber dimensions 12 inches x 14 inches x 6 inches
Operating range of 50°C to 1125°C
90 day warranty
The Fisher model 650-58 furnace provides microprocessor controlled heat at temperatures between 50°C and 1125°C (90° to 2057°F). Capable of up to 24 steps in program mode, a soak period of up to 23 hours 59 minutes and 59 seconds can be inserted between any two successive ramps. The digital display provides temperature and control readouts and LED indicators identify when heat is being applied or a fault is encountered.
The furnace chamber is molded from alumina silicate ceramic fibers for low thermal mass resulting in fast heat-up and cool down times. The unusually low external case temperatures enhance safety when working around the unit and the ventilated base prevents damage to the bench or countertop. The electric resistance heating elements ensure extended service life even in atmospheres surrounding high sulfur coal and coke samples.

Most of our equipment
is used and reconditioned. We test ovens using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.
The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
